Join Rudy Ramos for a weekly look at all things interesting, new, and noteworthy for design engineers.

The global renewable energy market has been experiencing substantial growth, driven by the increasing demand for clean and sustainable energy sources. Solar energy, in particular, has gained prominence as a key player in the renewable energy landscape. According to a report by Mordor Intelligence, the renewable energy market has now reached pre-pandemic levels, signifying its resilience and continued growth. This growth is attributed to various factors, including government incentives, technological advancements, and an increased awareness of environmental concerns.

The industry is constantly evolving to further enhance the efficiency and financial viability of photovoltaic (PV) systems. One critical aspect of this evolution is the need for 1500VDC PV systems. However, this transition presents challenges for DC-DC converters in supporting higher voltages. This week, we explore the progression and recent challenges of PV systems and consider how the solar market stands to benefit significantly from the AE15B-EW and AE15B-UW DC-DC converters from CUI Inc.

The Evolution of Photovoltaic Systems

To remain competitive and sustainable, photovoltaic systems must continuously improve their efficiency and financial viability. This drive for improvement stems from several considerations.

First, maximizing energy output. Efficiency is fundamental in solar energy generation. By increasing the efficiency of PV systems, more energy can be harnessed from the same amount of sunlight. This leads to higher energy production and better returns on investment. Facilities like the National Renewable Energy Laboratory (NREL), part of the US Department of Energy, regularly conduct testing of PV cells (Figure 1) and modules to ensure consistency and accuracy of PV performance metrics.

Second, reducing the installation costs. Financial viability is a crucial aspect of any solar project. Lowering installation costs, such as hardware and labor, can make solar energy more affordable for consumers and businesses alike. This is essential for the widespread adoption of solar technology.

Lastly, adapting to new technologies. The solar industry must continually adapt to emerging technologies, such as advanced materials and improved manufacturing processes. These innovations contribute to both increased efficiency and reduced costs.

The Need for 1500VDC Photovoltaic Systems

One significant development in the solar industry is the transition from traditional 1000VDC PV systems to 1500VDC PV systems. This increase in voltage has several advantages. Primarily, it improves the overall energy transmission. Stepping up to higher voltage systems allows for efficient electricity transmission over longer distances. This is particularly beneficial for large-scale solar installations and solar farms. Increasing the voltage also helps to mitigate electrical losses during energy transmission, resulting in less energy waste, thereby contributing to higher overall system efficiency. Also, 1500VDC systems require fewer electrical components, such as cables and connectors, leading to cost savings during installation and maintenance.

Challenges for DC-DC Converters in 1500VDC Systems

While the transition to 1500VDC PV systems offers numerous benefits, it also presents challenges for DC-DC converters, which play a critical role in these systems. For instance, DC-DC converters must be capable of handling the increased voltage levels in 1500VDC systems. This requires robust and reliable components to ensure safety and system stability.

Also, system efficiency is critical. Maintaining high efficiency levels in DC-DC converters is essential to maximize the energy harvested from solar panels. Any loss in efficiency can impact the overall performance of the PV system. Lastly, solar installations often operate in harsh environments with temperature variations and exposure to the elements, meaning DC-DC converters must be rugged and reliable to withstand these conditions over an extended period.

STSPIN32G4, The 1st motor controller with an integrated MCU solves 2 major challenges

Thu, 03/28/2024 - 06:58

Author: STMicroelectronics

The STSPIN32G4 integrates a three-phase gate driver, an STM32G431, and a power management system under one package to solve major engineering challenges, thus enabling new applications. While ST continues to offer STSPIN motor drivers, we also realized that engineers still face several conundrums. Designers want to run more powerful applications but must also shrink their PCBs and reduce costs. Similarly, applications demand more efficiency, but improving it by a few decimal percentage points remains a struggle. ST engineers thus launched the STSPIN32G4 because no other integrated motor controller offered such a powerful mainstream MCU and such a flexible power management system.

STSPIN32G4 and the first challenge: How to make things more powerful in a smaller design? More power under one roof The STSPIN32G4The STSPIN32G4

Let’s take the example of an engineer working on a high-end vacuum cleaner with a high-speed motor. The MCU inside the STSPIN32G4 will stand out, in this instance, because of its computational throughput. A lower-performance CPU core means a lower conversion rate when designing a field-oriented control (FOC) sensorless application. The engineer in the vacuum cleaner example would have to use two or three shunt resistors to compensate for the MCU’s lower performance. On the other hand, the greater computational throughput means a single shunt is sufficient. As a result, using the STSPIN32G4 enables the creation of a powerful application with fewer components.

More peripherals in one device

A team working on a collaborative robot or a guided vehicle would also appreciate the MCU in the STSPIN32G4 for reasons other than the bump in DMIPS. In this instance, engineers must drive two sets of wheels, but traditional motor controllers don’t have enough analog-to-digital converters to handle such a task. As a result, engineers end up using two motor drivers. The STSPIN32G4 is unique because it provides two sets of PWM timers and 12-bit ADCs, among other things. It, therefore, becomes possible to drive two motors with just one integrated device.

Saving 65% space

While it’s impossible to enumerate all the features in the STSPIN32G4, the reality is that its integrated nature is one of the best ways to solve the space challenge. Motor control applications are increasingly smaller, whether for convenience, costs, or to stand out better. Thanks to its integrated nature, the STSPIN32G4 helps reduce the overall design size by 65% compared to discrete solutions. Practically, it allows engineers to put the control system at the back of the motor and design a much smaller e-bike, vacuum cleaner, or power tool, among other things.

STSPIN32G4 and the second challenge: how to make things more energy efficient while keeping costs down? A more efficient power management

According to our benchmarks, using the new device lowers the overall power consumption by 3% to 5% compared to a system that uses external components. A saving of just a single percent already has a significant impact. ST provided such power efficiency by bringing the typical standby consumption to only 15 µA thanks to a very low-quiescent regulator. Hence, we expect engineers to create significantly more compact designs without needing an external cooling system, thus lowering the BoM.

The motor controller also supports a supply voltage of up to 75 V, compared to only 48 V previously. Additionally, the STSPIN32G4 comes with an over-current protection mechanism and a drain-source voltage (VDS) monitoring system that acts as a redundancy. It monitors the external MOSFETs and turns all gate driver outputs off if it detects an over-voltage condition. As a result, we expect engineers to use the STSPIN32G4 in appliances. Indeed, a white good connected to a grid often suffers from wide voltage variations from the mains. The greater supply voltage range and protection features of the new device will better handle these abnormal conditions.

A more flexible power management

Engineers sometimes shy away from integrated solutions, fearing they may restrict their optimization capabilities. Hence, ST ensured a high level of customization. For instance, developers can program registers through an I2C interface to use the STSPIN32G4’s VCC buck converter. Moreover, we published an application note showing how to use the buck regulator in a buck-boost configuration by adding a few external components. Finally, engineers can bypass the buck and LDO regulators to rely on only an external Vcc supply.

Teams that designed a highly precise power supply to meet the stringent requirements of their application can, thus, ignore the STSPIN32G4 regulators. In contrast, others can simplify their designs by using its VCC buck converter to power a few external components, like a memory module. Similarly, developers can choose to enable or disable the standby mode. Such a feature is vital for products like power tools. When users pick a drill after months or even years, they must use it immediately. In such a case, engineers will want to completely disconnect their system from the battery to maximize its usage.

Engineers also get a lot more flexibility in how they drive a motor. They could use a 6-step driver circuit or a field-oriented control, both with or without a sensor and with one, two, or even three shunts. It gives developers the ability to control how much measurement data they gather. Consequently, it also becomes possible to qualify an STSPIN32G4 and use it in many different applications, which can help a company shorten its time to market and optimize its operations.

How to get started The EVSPIN32G4The EVSPIN32G4

ST launched two development boards to enable teams to test and experiment with the STSPIN32G4. The EVSPIN32G4 uses STL110N10F7 power MOSFETs and a heat sink to allow an output current of up to 20 A RMS. As a result, teams can push the new devices to develop more powerful designs. However, ST is also mindful that not every designer will use the STSPIN32G4 in high-powered systems. Hence, we are also launching the EVSPIN32G4NH, a similar development board without passive cooling; NH at the end of the nomenclature stands for “no heat sink”. We also updated the X-CUBE-MCSDK to support the new boards and devices.

The EVLSPIN32G4-ACTThe EVLSPIN32G4-ACT

More recently, our teams released two reference designs. The EVLSPIN32G4-ACT drives a three-phase brushless motor supporting up to 5 ARMS and can manage a supply input of 48 V for a surprising 250 W total power in a board measuring only 62 mm x 50 mm. Additionally, it can connect to the STWIN.box (STEVAL-STWINBX1) to rapidly create a high-speed data logger. Thanks to our FP-IND-DATALOGMC software pack and Quick Start Guide, engineers have a step-by-step process to connect both boards and run applications that can gather data from the sensors on the STWIN.box and the motor itself. We even offer a GUI to help visualize the information.

The EVSPIN32G4-DUALThe EVSPIN32G4-DUAL

The other board is the EVSPIN32G4-DUAL, which combines the STSPIN32G4 and the STDRIVE101, a triple half-bridge gate driver. As a result, the board can drive two three-phase brushless motors for up to 10 ARMS output current and a supply of 74 V thanks to two power stages. Thanks to the operational amplifiers of the STSPIN32G4, it’s possible to have a sensor-less system with a single shunt current sensing or use Hall sensors and encoders with the embedded MCU. Put simply, the reference design shows how to create a powerful dual motor application in a small factor for home appliances, e-mobility, pumps, tools, and more.

CS extends the positioning capabilities of low energy devices based on high accuracy distance measurements. The R&S CMW platform offers fully featured RFPHY test capabilities using the phase-based ranging (PBR) principle. High-performance internal signal generators and analyzers allow repeatable high-quality device verification.

The R&S CMW platform also supports Bluetooth® Low Energy over-the-air (OTA) receiver and transmitter measurements, as defined in the upcoming Unified Test Protocol (UTP) test mode. The OTA test capability allows easy RFPHY testing of devices that do not have a physical test connector. The new Bluetooth core specification defining the CS and UTP modes is expected to be released later this year.

The R&S CMW platform is a comprehensive, fully automated test solution for verifying the physical layer functions Bluetooth Low Energy and Bluetooth Classic with the addition of LE audio measurements. Visitors can experience the new LE test modes live at the Rohde & Schwarz booth.

Eight-channel MXO 5 oscilloscope sets new signal analysis standards

Another highlight is the MXO 5 oscilloscope from Rohde & Schwarz, the world’s first eight-channel oscilloscope that can detect 4.5 million acquisitions and a total of 18 million waveforms per second across multiple channels. The MXO 5 shows more of a signal’s activity than any other oscilloscope in both the time and frequency domains. With a simultaneous acquisition memory of 500 Mpoints across all eight channels, it offers twice the standard memory of competitive models. As the first eight-channel oscilloscope with digital triggering, it sets a new standard for signal analysis. It is also the first oscilloscope to offer 45 000 FFTs per second. Visitors to the Rohde & Schwarz booth will have the opportunity to see this innovative instrument in action, testing system-on-chip (SoC) power designs with multiphase buck converters.

Testing signal integrity in high-speed digital designs

High-speed digital interfaces play a pivotal role in electronic designs. Increasing data rates and integration densities are a challenge for designs at the IC, board and system levels. Visitors to the show can learn about powerful tools for system verification and debug, as well as compliance testing for signal integrity in interfaces, PCBs and interconnects, directly from experts in the field. Demo setups at the Rohde & Schwarz booth include USB 3.2 signal integrity debugging with receiver equalization emulation and advanced eye diagram analysis with the R&S RTP164B oscilloscope, as well as protocol decoding with the MXO 4 oscilloscope.

In addition, visitors will find a solution for fully automated (pre-)compliance testing and verification of high-speed cables (IEEE 802.3bj/by/cd/ck and PCIe 5.0/6.0) using the R&S ZNrun automation test suite, an R&S ZNA or R&S ZNB vector network analyzer and the R&S OSP320 open switch and control platform. The multiport physical layer analysis of a PCIe 6.0 compliant cable is performed by accurately de-embedding the signal with the R&S ZNB43 vector signal analyzer.

R&S CMX500 with new Wi-Fi 7 R&D capabilities

The new Wi-Fi 7 standard supports up to 16×16 MIMO with 320 MHz wide channels and 4096 QAM modulation, providing extremely fast and stable connections. When developing Wi-Fi 7 devices, the RF TX and RX characteristics must be measured under real-world conditions in signaling mode. The R&S CMX500 multi-technology multi-channel signaling tester is now available with integrated Wi-Fi 7 test functions. Test environments with multiple RF chains are particularly important in Wi-Fi 7, where multilink operation (MLO) is a key feature. The tester’s flexibility, support for multiple radio technologies and embedded IP test capabilities make it a versatile solution for a wide range of Wi-Fi 7-specific tests, such as 2×2 MIMO, 6 GHz band with out-of-band discovery, coexistence and E2E test capabilities.

Solving test challenges for UWB verification and FiRa Consortium certification

Accurate ranging, low power consumption, high security and reliability – these are the features of ultra-wideband (UWB) technology features that make it suitable for many secure ranging applications, especially as a digital key. At embedded world 2024, Rohde & Schwarz will present the R&S CMP200 radio communication tester with integrated UWB test capabilities for solving UWB test challenges in mass production as well as in R&D.

Analyzing and debugging electromagnetic emissions

Because all electronic controllers are susceptible to conducted or radiated electromagnetic emissions, many finished electronic products fail their first EMC compliance test. Every day spent debugging, isolating and correcting the EMI problem increases the time to market. As a leader in EMC testing, Rohde & Schwarz will present solutions that integrate EMI testing into the product design process. Visitors can learn how to use the powerful R&S RTO6 oscilloscope for EMI debugging or the R&S FPL1000 signal and spectrum analyzer for EMC pre-compliance testing.

EMC compliance testing

Rohde & Schwarz offers the R&S ESW EMI test receiver for final EMC compliance tests. With the new R&S ESW-B1000 wideband option, the R&S ESW can expand its FFT bandwidth to up to 970 MHz to measure the complete CISPR frequency Bands C and D in a single operation. The wide bandwidth helps to intercept sporadic interference and enables higher reliability and repeatability in commercial and MIL-STD tests. The extremely high measurement speed opens up new possibilities for compliance testing as well as for emissions analysis and debugging. The R&S EPL1000 EMI test receiver offers fast, accurate and reliable EMI compliance measurements up to 30 MHz at a competitive price in the full CISPR 16-1-1 compliance receiver class for both device developers and conformance test houses.

Battery simulation and power consumption testing

Battery life is usually one of the most important specifications for battery-powered devices. Visitors can explore the R&S NGM200 high-precision DC power supply in a battery testing and simulation setup. The application software facilitates battery discharging, as well as the repeated discharge and recharge of rechargeable batteries. Continuous monitoring and recording of open circuit voltage and voltage under load are integral features. The DC power supply can be remotely controlled from a PC with the application software installed.

Another test setup allows visitors to use various smartwatch apps to observe how GPS affects power consumption in real time. A new analysis tool helps developers analyze power consumption data collected with the R&S NGU power supply. These source measure units can be used for battery modeling and simulation. They measure the current consumption of battery-powered devices in all phases and during the transition from sleep to active mode, which is important for design engineers.

Component testing: high speed VCO tester and an LCR meter with sweep software

Rohde & Schwarz will present its R&S FSPN high-speed phase noise analyzer up to 50 GHz in a demonstration test setup with a VCO device under test. Equipped with two low phase noise synthesizers and a real-time cross-correlation engine for increased measurement sensitivity, it is ideal for characterizing sensitive synthesizers and oscillators in R&D. In addition, Rohde & Schwarz will showcase its R&S LCX200 LCR meters with customized impedance measurement functions that are suitable for all discrete passive components up to 10 MHz. Using the R&S LCX sweep software tool, they can even per­form sweep measurements displaying numerous charts. The MFIA impedance analyzer from Zurich Instruments AG (a subsidiary since 2021) will also be on display. The MFIA provides impedance analysis for both low and high impedance components and has a measurement mode for quickly tracking impedance changes in devices under test.
