I made a 1kW lab bench power supply from scratch

Hello r/electronics,

In this post, I want to share my project that I’ve been working on in the past few months. It’s a custom-built lab bench power supply. Such a project is common in the DIY community, so what makes this one different? The custom-designed SMPS board that I engineered from scratch isn’t your typical “let’s put this power supply module into a case” approach. So let’s dive into the working principles, design decisions, and in-depth test results.

The Forwarder 1kW is the SMPS board that I designed and used in this project. It’s based on a hard-switch, half bridge topology. The full features of this power supply are as follow:

  • 1000W maximum continuous output capacity.
  • Configurable from 50V/20A up to 400V/2.5A.
  • CC/CV mode with mode signal and indicator.
  • Tuneable operating frequency and dead-time.
  • Dedicated power stage enable pin.
  • Analog reference interface for output voltage/current control.
  • Analog signal output interface for monitoring voltage/current.
  • Dedicated fan port with optional automatic power-on.
  • Simple construction, less than 130 components on board.
  • Easy to build with mostly THT components.
  • Curated component selection for high accessibility.

The working principle of this design is about as simple as it can get for a switched-mode power supply. I talked about the working principle of my design over on r/AskElectronics, so I’m not going to repeat it here. Most of the concepts stay the same, just with some design adjustments and the numbers changed.

https://www.reddit.com/r/AskElectronics/comments/1s8ll9g/

Now, I want to go in detail about the design decisions that led into this design that you may find interesting.

  1. The lack of active PFC (Power Factor Correction) was determined after I reviewed many existing designs and products in the same power level and after noticing many of them get away without one, I decided to omit this feature. For my first SMPS design, I want to focus solely on the DC to DC conversion power stage. For my next iteration, I’m more likely to resort to a simple boost PFC to achieve tighter regulation.
  2. Double-ended hard-switch topology (half-bridge in particular) was chosen due to its suitability and simplicity in this application. Flyback is out of the question due to power requirement, single-ended topologies have poorer core utilisation and the high favour for current mode control, and resonant topologies don’t seem like a good choice for my first SMPS design (duh).
  3. An SG3525 with LM324 was chosen to generate the PWM signal and achieve regulation. SG3525 is quite popular for double-ended converters with plenty of documentation online, while the LM324 provides CC+CV regulation with two of its op-amps (because SG3525 only features one error amplifier). This effectively forms a setup based on voltage mode control.
  4. Voltage mode control was inherently chosen as the result of using SG3525 and it was favoured due to its “arguably” simpler implementation over current mode control. However, I find the better regulation and inherent cycle-by-cycle overcurrent protection offered in current mode control very enticing. I probably would resort to this approach for my next iteration.
  5. My galvanic isolation strategy was to have the entire control circuit on the secondary side and have the PWM signal driven to the primary through a gate drive transformer. This way, I can have simpler and more precise control over the voltage and current regulation without the nonlinearity issues of using optocouplers.
  6. ETD49 cores were used for both transformer and output inductor. I like the round bobbin that makes winding easier, and the calculations prove it’s suitable for power of 1kW at 64kHz. The gapped version was used for the output inductor because the high inductance requirement requires high turn number, and that gets complicated real quick with toroidal cores.

After I finished the board, I wanted to know how my design performs in real-life. So, I conducted a few tests that are relevant for a power supply. The testing rig was pretty simple:

  1. A power meter at the input and four DS18B20 were used to track the energy consumption and component thermal profile over time.
  2. An electrolysis tank with electrodes that can be spaced accordingly was used to simulate multiple load profiles at power up to 1kW.
  3. A third positive electrode connected through a toggle switch was used to abruptly step the load in the dynamic tests.
  4. Hantek DSO2D10 was used to capture the waveforms in various tests.

The test conducted, along with their results are as follow:

  1. The stress test was conducted for one hour and each component temperatures peaked at the following temperatures: half-bridge N-MOS 75°C / 167°F, main transformer 55°C / 131°F, output rectifier 69°C / 156°F, output inductor 44°C / 111°F.
  2. The efficiency characterisation was conducted at 50V and 1, 2, 5, 10, and 20 amps. 89% efficiency was achieved at 5A load or more. Maximum recorded efficiency was 90.3% at 50V 10A load, and efficiency at maximum load was 89.1%.
  3. The output ripple test was done with direct on-trace probing with a ground spring, 20M BW limit, 1x probe, and no added capacitor. No load ripple showed at 40mVpp, 1A load at 34mVpp, and maxes out at 94mVpp at full load.
  4. The turn-on curve tests showed that under loaded condition, it’s bound to the SG3525 soft start function and takes a second to reach the full 50V. At no load and lower setpoints, the voltage overshoots by a few volts.
  5. The load step tests showed about 3% voltage deviation going from no load to 10A and vice-versa. Going from 5A to 10A and vice-versa showed no sign of voltage deviation.
  6. CV to CC transition took 3ms to begin responding and a full 7ms until the voltage settled. CC to CV transition began immediately and took 3ms to settle. 50V CV to 10A dead-short showed 10App oscillation at 2.2kHz.
  7. The input bulk capacitor showed 24Vpp ripple and the DC blocking capacitor showed 14.2Vpp ripple. The primary side of the transformer showed about 75% overshoot that settled within 2 cycles.
  8. The N-MOS at conduction showed 184nS fall time for Vds and 572nS rise time for Vgs. At disconduction, the Vds rise time showed as 56nS and 556nS for Vgs fall time.

I’m here not to glaze over my design. After reviewing the results and doing a retrospective, here are my critical opinions about this design.

What I like about this design:

  • Good efficiency figure (89.1% at full-load)
  • Excellent ripple even without a second-stage filtration (94mVpp at full load)
  • Good power density for an almost-fully THT build.

What I don’t like about this design:

  • The overcurrent protection is too slow, though it somehow works at preventing the half-bridge from exploding on the dead-short test.
  • The compensator design fails in certain conditions (DCM/CCM transitions, output dead short), which results in output oscillation.
  • The output diodes are hard to access or replace.

The full schematic, gerber files, KiCAD save files, spreadsheet calculation, and full-res images are available on my Github repository: https://github.com/Luq1308/Forwarder1kW

The build process and the in-depth testing are available in my YouTube video: https://youtu.be/MGMqqtXgwRg

That’s all I have about this project. I hope this post is informative and can be used as a reference or for benchmarking purposes, in which I had difficulty in researching previously. If you have any unanswered questions, let me know and I’ll try to answer them. Thank you for reading, and I'll see you next time.

How AI is driving a new paradigm in test distribution

EDN Network - Wed, 06/24/2026 - 19:19

Artificial intelligence (AI) is accelerating semiconductor innovation at a pace that is forcing a rethinking of conventional production test strategies. The rapid scaling of graphics processing units (GPUs), AI accelerators, and heterogeneous compute architectures is increasing not only device complexity, but also the amount of test content required to validate performance, reliability, and quality across the manufacturing flow.

As AI infrastructure investments continue to expand, semiconductor manufacturers are building increasingly sophisticated devices that combine massive transistor counts, advanced packaging, high-bandwidth memory (HBM), chiplet architectures, and emerging co-packaged optical (CPO) interfaces. These devices are redefining the relationship between design, validation, and production test.

The result is a new test paradigm in which test content, infrastructure, and analytics are distributed dynamically across multiple insertions—from wafer sort through system-level test (SLT)—to balance cost-of-test, defective-parts-per-million (DPPM), and time-to-market objectives.

 

AI devices driving a step change in test requirements

The transition from monolithic devices to heterogeneous multi-die systems has substantially increased the burden on automated test equipment (ATE). AI processors now incorporate far more compute engines, memory bandwidth, and power-delivery complexity than previous generations of high-performance devices.

At the same time, traditional transistor scaling no longer delivers the same gains once associated with Moore’s Law. To continue improving system performance, designers are adopting More-than-Moore integration strategies that combine chiplets, 3D packaging, integrated voltage regulation, and advanced interconnect technologies within increasingly dense package architectures. These changes are producing several cascading effects on tests.

First, scan and functional test workloads are growing dramatically as transistor counts increase. Modern AI devices require extremely large volumes of scan vectors that must be delivered at gigabit-per-second speeds through either massively parallel digital channels or high-speed serial interfaces such as PCIe and USB.

Second, power requirements are rising rapidly. Device power supplies must now support kiloamp-class current delivery while maintaining tight regulation and accuracy under highly dynamic loading conditions. Flexible power architectures capable of extensive channel ganging are becoming increasingly important as final-test power envelopes continue to climb.

Thermal management is becoming equally critical. AI devices entering production are expected to push package-level power dissipation into multi-kilowatt ranges, making active thermal control essential throughout the test flow. In advanced environments, thermal systems are increasingly paired with predictive analytics capable of anticipating thermal excursions before they occur, enabling proactive cooling and tighter junction-temperature management.

Advanced packaging complicates multisite test

Migration toward larger 2.5D and 3D packages is also changing the physical realities of production test. As package sizes expand to accommodate more chiplets, HBM stacks and photonic components, device handling and multisite efficiency become more difficult to optimize. Larger sockets consume increasing amounts of device-under-test (DUT) board real estate, constraining routing resources and limiting tester scalability.

In parallel, manufacturers are moving toward larger tray formats carrying fewer devices per tray because of package dimensions and handling constraints. These shifts reduce some of the traditional efficiencies associated with high-parallelism production environments.

The addition of photonic and CPO technologies introduces another layer of complexity. Optical interfaces require integrated electro-optical validation across multiple stages of manufacturing, extending test coverage well beyond conventional electrical characterization. As a result, optical instrumentation is increasingly being introduced at wafer probe, optical-engine test, final package test, and SLT insertions.

Test engineering becoming more software- and data-centric

The growing complexity of AI devices is changing not only hardware requirements, but also the nature of test engineering itself. In other words, engineering organizations are under pressure to accelerate bring-up, reduce debug cycles, and maintain quality targets despite rapidly increasing test content volumes. This is driving tighter integration between design, silicon validation, and manufacturing teams.

As a result, AI-assisted software tools are beginning to play a larger role in test-program generation, debug optimization, and adaptive workflow management. Real-time analytics platforms can now aggregate data across multiple insertions, enabling faster correlation of failures and more intelligent allocation of test coverage throughout the production flow.

In these environments, test content is no longer statically assigned to a single insertion. Instead, coverage increasingly shifts throughout the flow depending on where defects can be detected most efficiently and economically. This distributed approach to test is becoming essential as AI devices scale toward trillion-transistor complexity.

Shifting test left reduces packaging risk

One major trend is the movement of more test content earlier in the manufacturing flow. For advanced AI devices, packaging costs now represent a substantial portion of total product cost because of technologies such as HBM and chip-on-wafer-on-substrate (CoWoS) integration. Packaging defective die into expensive multi-die assemblies can significantly increase material waste and reduce yield.

To mitigate this risk, manufacturers are pushing more coverage to wafer-level and die-level test insertions to improve known-good-die confidence before assembly. Figure 1 illustrates how test distribution increasingly spans the entire workflow, with tighter interaction between design, validation, and production environments.

Figure 1 Test distribution has expanded to accommodate growing need for test across the manufacturing ecosystem—beginning with silicon validation and extending through system-level test. Source: Advantest

This shift-left strategy (Figure 2) includes broader scan coverage and expanded fault modeling at speed testing, and increasingly system-aware functional validation at the die level. Some workflows also incorporate calibration, trimming, and memory repair operations prior to package assembly.

Figure 2 Shifting test content left enables more coverage at wafer and die test stages to improve known-good-die screening before package assembly. Source: Advantest

In more advanced implementations, active thermal control capabilities are also migrating closer to singulated-die test stages. The objective is straightforward: identify marginal or defective components before they enter expensive advanced-packaging flows.

System-level test expanding

At the same time, other forms of coverage are shifting later in the process. As devices become more heterogeneous and application-specific, certain failure mechanisms emerge only under realistic operating conditions involving software execution, thermal loading, timing interactions, or high-bandwidth traffic patterns.

These conditions are often difficult—or impossible—to replicate during traditional structural or functional test insertions. Consequently, SLT is becoming increasingly important for AI and HPC devices. System-level environments can expose defects associated with workload execution, protocol interactions, and real-world operating states that are not observable during earlier production stages.

New approaches, including scan-over-PCIe methodologies and highly parallel SLT architectures, are helping manufacturers improve coverage while attempting to control the significant test times associated with these environments. Figure 3 illustrates the corresponding shift-right strategy.

Figure 3 Shifting test content right enables additional test coverage to be executed after packaging to further reduce DPPM before shipment. Source: Advantest

Real-time analytics enabling adaptive test distribution

The increasing fragmentation of test insertions is creating demand for tighter orchestration across the production floor. Modern test infrastructures are evolving toward highly connected environments in which data streams continuously between validation, wafer sort, final test, and SLT operations. Real-time analytics platforms can then use this data to optimize insertion decisions, adapt test limits, and improve yield-learning cycles.

GPU-accelerated edge inferencing and AI-based decision engines are also enabling faster adaptive responses during production. In some cases, computation can be offloaded from the tester itself to remote compute infrastructure, allowing more sophisticated analytics without compromising throughput.

This level of coordination requires consistent software frameworks and portable test content capable of moving seamlessly between insertions and platforms. So, shared execution environments and unified debug tools are becoming increasingly important as manufacturers attempt to reduce engineering overhead while accelerating deployment.

Optical test adds new workflow stages

CPO and photonic integration introduce additional challenges because optical functionality must be validated alongside traditional electronic behavior. Unlike conventional semiconductor devices, photonic systems often require multiple dedicated insertion points throughout manufacturing. These may include photonic wafer test, dual-sided probing of electronic and photonic die, optical-engine characterization, and additional packaged-module validation after integration with ASICs.

As with electrical tests, much of this optical validation is shifting earlier in the flow to ensure known-good optical engines prior to final assembly. However, full electro-optical verification often still requires additional socketed final-test and SLT insertions after system integration.

Figure 4 highlights how optical test introduces additional insertion points spanning photonic wafer test, optical-engine validation, final package test, and SLT.

Figure 4 For testing CPO devices, test content shifts left for three insertions and right for final socketed device test. Source: Advantest

Test distribution is becoming a strategic optimization problem

AI is transforming semiconductor tests from a relatively linear production step into a highly distributed optimization challenge involving power, thermal management, data analytics, packaging economics, and workflow orchestration. Meeting future quality and throughput requirements will require closer collaboration across the semiconductor ecosystem, including design teams, ATE suppliers, packaging providers, and system integrators.

As AI devices continue scaling in complexity, test infrastructure must evolve from traditional defect screening toward intelligent, adaptive validation environments capable of making real-time decisions across the manufacturing flow. In that sense, the future of semiconductor test may depend as much on data movement and workflow intelligence as on the tester hardware itself.

Capacitive position sensor with linearized output

EDN Network - Wed, 06/24/2026 - 15:00

An only slightly less simple followup circuit also ratios sensor capacitance to a reference capacitor to measure micrometers…this time linearly.

A few weeks ago, Design Ideas published a simple circuit of mine that provides an analog interface to capacitive position sensorsFigure 1 shows that basic design with its separate complementary outputs: Out and –Out.

Wow the engineering world with your unique design: Design Ideas Submission Guide


Figure 1 The U1a and U1b cross-coupled Schmidt trigger timers form a ~1MHz RC multivibrator. The Tsense pulse width is inversely proportional to sensor displacement (Tref/Tsen= Cref/Csen = d).

Figure 2 shows the “Simple Simon” method it offered for acquisition of the sensor position signal: passive RC averaging of the Tsense pulse train.


Figure 2 Passive RC averaging of the Tsense output yields the analog position output.

The resulting analog output, as shown in figure 3, provides good range and resolution but is nonlinear.


Figure 3 This graph shows the sensor performance when Out is connected to a 12bit ADC using +5V for its reference. The black curve (left axis) equals the plate separation (d) in millimeters. The red curve (right axis) equals the ADC lsb resolution in micrometers.

So, I got to thinking about linearization and the advantages it would provide, and wondering how tough it would be.  It turned out to be not that difficult. 

Figure 4 shows the resulting interface with added linearization circuitry.  Just an added opamp, three resistors, and two non-critical caps did the trick.  Here’s how it works.


Figure 4 Averaging integrator A1 linearizes the displacement sensing response.  R5 is shown as a precision type, albeit just out of force of habit.  It, like the ON resistances of U2’s switches, actually cancels out.

Each capacitance measurement cycle, the 500ns Tref pulse causes 4066 switch U2d to deposit a quantum of charge on integrator A1’s summing node of Qref = Tref/R5.  Meanwhile the sensor-capacitance proportional Tsen pulse subtracts Qsen = Tsen(Vout – 1)/R5.  The charge balance is forced by A1 to maintain Qsen = Qref, therefore Tsen(Vout – 1)/R5 = Tref/R5, and Vout – 1 = Tref/Tsen = Cref/Csen = d. Note that R5 magically (?) disappears from the math.

Figure 5 shows the straight-as-an-arrow-in-zero-gravity result.


Figure 5 In this graph of the enhanced circuit results, the black curve equates to the sensor readout d in mm, with red at a constant 1 mV per micron resolution.

Stephen Woodward‘s relationship with EDN’s DI column goes back quite a long way. Over 200 submissions have been accepted since his first contribution back in 1974.  They have included best Design Idea of the year in 1974 and 2001.
