In the realm of lighting, one of the most iconic and enduring symbols is the filament bulb. While newer technologies have emerged, the filament bulb continues to hold a special place in our hearts and homes. In this blog, we delve into the world of filament bulbs, exploring what they are, how they work, their uses, and their advantages.

What is a Filament Bulb?

A filament bulb, also known as an incandescent bulb, is a type of light bulb that produces light by heating a thin tungsten wire filament to a high temperature until it glows. The filament is housed within a glass bulb filled with inert gas to prevent the filament from oxidizing and burning out too quickly.

How Does a Filament Bulb Work?

The principle behind the operation of a filament bulb is simple yet elegant. When an electric current passes through the filament, it encounters resistance, which causes the filament to heat up. As the temperature rises, the filament emits light in the visible spectrum, illuminating its surroundings.

Filament Bulb Uses

Filament bulbs have been a staple in lighting applications for over a century. While their popularity has waned with the advent of more energy-efficient alternatives, filament bulbs still find use in various settings, including:

1. Decorative Lighting: Filament bulbs are prized for their warm, inviting glow, making them a popular choice for decorative lighting in homes, restaurants, and cafes.
2. Vintage Aesthetics: With their classic design and nostalgic appeal, filament bulbs are often used in vintage-inspired interiors, adding a touch of old-world charm.
3. Display Lighting: Filament bulbs are ideal for highlighting merchandise in retail displays, creating an attractive ambience that draws customers’ attention.
4. Special Events: From weddings to outdoor parties, filament bulbs are a popular choice for creating a festive atmosphere, casting a warm and inviting glow over gatherings.

Filament Bulb Advantages

While filament bulbs may not be as energy-efficient as their LED counterparts, they still offer several advantages that make them a preferred choice in certain scenarios:

1. Warmth and Ambiance: Filament bulbs emit a warm, soft light that closely resembles natural sunlight, creating a cozy and inviting atmosphere wherever they are used.
2. Instant On: Unlike some energy-saving bulbs that require time to reach full brightness, filament bulbs provide instant illumination, making them ideal for areas where immediate light is needed.
3. Dimmable: Many filament bulbs are dimmable, allowing users to adjust the brightness to suit their preferences and set the mood for different occasions.
4. Affordability: Filament bulbs are often more affordable than LED bulbs, making them a cost-effective lighting solution for those on a budget.
5. Compatibility: Filament bulbs are compatible with most standard fixtures, making them an easy and convenient replacement for traditional incandescent bulbs.

In Conclusion

While filament bulbs may no longer be the go-to choice for energy-conscious consumers, their timeless appeal and unique characteristics continue to make them a popular lighting option in many settings. Whether used for decorative purposes, vintage aesthetics, or special events, filament bulbs shine bright as a symbol of illumination’s enduring legacy.

Microchip Technology Inc. launches a new family of integrated motor drivers, leveraging its dsPIC Digital Signal Controllers (DSC). This innovative solution integrates a dsPIC33 DSC, a three-phase MOSFET gate driver, and an optional LIN or CAN FD transceiver into a single package. It provides a comprehensive solution for efficient, real-time embedded motor control in space-constrained applications.

This integration reduces the components needed for motor control system designs, leading to smaller PCB sizes and simplified design complexity. Particularly beneficial for automotive, consumer, and industrial applications where high performance and compact form factors are crucial.

Key Features Include:

• Single power supply operation up to 29V (operation) and 40V (transient).
• Internal 3.3V low dropout (LDO) voltage regulator for the dsPIC DSC.
• Operating frequencies between 70—100 MHz, enabling high CPU performance for advanced motor control algorithms like field-oriented control (FOC).

Artificial Intelligence is currently driving an exponential increase in global data generation, and consequently increasing the energy demands of the chips supporting this data growth. Today, Infineon Technologies AG launched its TDM2254xD series dual-phase power modules that enable best-in-class power density, quality and total cost of ownership (TCO) for AI data centres. The TDM2254xD series products blend innovation in robust OptiMOSTM MOSFET technology with novel packaging and proprietary magnetic structure to deliver industry-leading electrical and thermal performance with robust mechanical design. This lets data centres operate at a higher efficiency to meet the high power demands of AI GPU (Graphic Processor Unit) platforms while also significantly reducing TCO. 

Given that AI servers require 3 times more energy than traditional servers and data centres already consume more than 2 per cent of the global energy supply, it is essential to find innovative power solutions and architecture designs that further drive decarbonization. Paving the way for the green AI factory, Infineon’s TDM2254xD dual-phase power modules combine with XDPTM Controller technology to enable efficient voltage regulation for high-performance computing platforms with superior electrical, thermal and mechanical operation.

Infineon introduced the TDM2254xD series at the Applied Power Electronics Conference (APEC). The modules’ unique design allows for efficient heat transfer from the power stage onto the heat sink through a novel inductor design that is optimized to transfer current and heat, thereby allowing for a 2 per cent higher efficiency than industry average modules at full load. Improving power efficiency at the core of a GPU yields significant energy savings at scale. This translates into megawatts saved for data centres computing generative AI and in turn leads to reduced CO2 emissions and millions of dollars in operating cost savings over the system’s lifetime. 

“This unique Product-to-System solution combined with our cutting-edge manufacturing lets Infineon deliver solutions with differentiated performance and quality at scale, thereby significantly reducing total cost of ownership for our customers,” said Athar Zaidi, Senior Vice President of Power & Sensor Systems at Infineon Technologies. “We are excited to bring this solution to market; it will accelerate computing performance and will further drive our mission of digitalization and decarbonization.”

When analog circuits mix with digital, the former are sometimes dissatisfied with the latter’s usual single supply rail. This creates a need for additional, often negative polarity, voltage sources that are commonly provided by capacitive charge pumps.

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

The simplest type is the diode pump, consisting of just two diodes and two capacitors. But it has the inherent disadvantages of needing a separately sourced square wave to drive it and of producing an output voltage magnitude that’s at least two diode drops less than the supply rail. 

Active charge pump switches (typically CMOS FETs) are required to avoid that.

Many CMOS charge pump chips are available off the shelf. Examples include the multi-sourced ICL7660 and the Maxim MAX1673 pumps that serve well in applications where the current load isn’t too heavy. But they aren’t always particularly cheap (the 1673 for example is > $5 in singles) and besides, sometimes the designer just feels the call to roll their own. Illustrated here is an example of the peculiar outcomes that can happen when that temptation isn’t resisted.

The saga begins with Figure 1, showing a (vastly simplified) sketch of a CMOS logic inverter.

Figure 1 Simplified schema of typical basic CMOS gate I/O circuitry showing clamping diodes and complementary FET switch pair.

Notice first the input and output clamping diodes. These are included mainly to protect the chip from ESD damage, but a diode is a diode and can therefore perform other useful functions, too. Similarly, the P-channel FET pair was intended to connect the V+ rail to the output pin when outputting a logic ONE, and the N-channel for connection to V- to pin for a ZERO. But CMOS FETs will willingly conduct current in either direction when ON. Thus, current running from pin to rail works just as well as from rail to pin. 

Figure 2 shows how these basic CMOS facts relate to charge pumping and voltage inversion.

Figure 2 Simplified topology of logic gates comprising voltage inverter, showing driver device (U1), switch device (U2), and coupling (Cc), pump (Cp), and filter (Cf) capacitors.

 Imagine two inverters interconnected as shown in Figure 2 with a square wave control signal coupled directly to U1’s input and through DC blocking cap Cc to U2’s with U2’s input clamps providing DC restoration.

Consider the ZERO state half cycle of the square wave. Both U1 and U2 P-channel FETs will turn on, connecting the U1 end of Cp to V+ and the U2 end to ground. This will charge Cp with its U1 terminal at V+ and its U2 end at ground. Note the reversed polarity of current flow into U2’s output pin due to Cp driving the pin positive and from there to ground through U2’s P FET and positive rail pin.

Then consider what happens when the control signal reverses to the ONE state.

Now the P FETs will turn OFF while the N FETs turn ON. This forces the charge previously accepted by Cc to be dumped to ground through U1 and its complement drawn from U2’s V- pin, thus completing a charge-pumping cycle that delivers a quantum of negative charge:

Q- = -(CpV+ + Cf V–)

to be deposited on Cf. Note that reversed current flow through U2 occurs again. This cycle will repeat with the next reversal of the control signal, and so on, etc., etc.

During startup, until sufficient voltage accumulates on Cf for normal operation of internal gate circuitry and FET gate drive, U2 clamp diodes serve to rectify the Cp drive signal and charge Cf.

That’s the theory. Translation of Figure 2 into practice as a complete voltage inverter is shown in Figure 3. It’s really not as complicated as it looks.

Figure 3 Complete voltage inverter: 100 kHz pump clock (set by R1C1), Schmidt trigger and driver (U1), and commutator (U2).

 A 100 kHz pump clock is output on pin 2 of 74AC14 Schmidt trigger U1. This signal is routed to the five remaining gates of U1 and the six gates of U2 (via coupling cap C2). Negative charge transfer occurs through C3 into U2 and accumulates on filter cap C5.

Even though the Schmidt hysteresis feature isn’t really needed for U2, the same type is used for both chips to improve efficiency-promoting synchronicity of charge-pump switching.

Some performance specs (V+ = 5V):

• Impedance of V- output: 8.5 Ω
• Maximum continuous load: 50 mA
• Efficiency at 50 mA load: 92%
• Efficiency at 25 mA load: 95%
• Unloaded power consumption: 440 µW
• Startup time < 1 millisecond

But finally, is there a cost advantage to rolling your own? Well, in singles, the 1673 is $5, the 7660 about $2, but two 74AC14s can be had for only a buck. The cost of passive components is similar, but this DI circuit has more solder joints and occupies more board area. So, the bottom line…??

But at least using outputs as inputs and ground as an output was fun.

And an afterthought: For higher voltage operation, simply drop in CD4106B metal-gate chips for the 74AC14s, then with no other changes, V+ and V- can be as high as 20V.

Stephen Woodward’s relationship with EDN’s DI column goes back quite a long way. Over 100 submissions have been accepted since his first contribution back in 1974.

A corresponding ecosystem of support tools will help simplify motor control system development and accelerate time to market

To implement efficient, real-time embedded motor control systems in space-constrained applications, Microchip Technology has launched a new family of dsPIC Digital Signal Controller (DSC)-based integrated motor drivers. These devices incorporate a dsPIC33 digital signal controller (DSC), a three-phase MOSFET gate driver and an optional LIN or CAN FD transceiver into one package. A significant benefit of this integration is reduction in component count of the motor control system design, smaller printed circuit board (PCB) dimensions and reduced complexity. The devices are supported by development boards, reference designs, application notes and Microchip’s field-oriented control (FOC) software development suite, motorBench Development Suite V2.45.

“Automotive, consumer and industrial designs are evolving and require higher performance and reduced footprints. These expectations often come at a higher expense and increase in dimensional size,” said Joe Thomsen, vice president of Microchip’s digital signal controllers business unit. “By integrating multiple device functions into one chip, the dsPIC DSC-based integrated motor drivers can reduce system-level costs and board space.”

The integrated motor driver devices can be powered by a single power supply up to 29V (operation) and 40V (transient). An internal 3.3V low dropout (LDO) voltage regulator powers the dsPIC DSC, which eliminates the need for an external LDO to power the device. Operating between 70—100 MHz, the dsPIC DSC-based integrated motor drivers provide high CPU performance and can support efficient deployment of FOC and other advanced motor control algorithms.

Development Tools

An extensive ecosystem of motor control software and hardware development tools helps make the design process faster and easier, reducing the customer’s time to market.

The dsPIC33CK Motor Control Starter Kit (MCSK) and the MCLV-48V-300W are two new dsPIC33-based integrated motor driver development boards that provide rapid prototyping solutions with flexible control options. The MCSK includes a dsPIC33CK low-voltage motor control development board, a 24V three-phase BLDC motor, an AC/DC adapter, a USB cable and other accessories. This cost-effective kit supports fast prototyping of motor control applications that operate between 12 and 48 VDC with up to 10 Amps of continuous current. The MCLV-48V-300W development board enables fast prototyping of three-phase permanent magnet synchronous motors that are rated between 12 and 48 VDC and capable of delivering up to 25A RMS continuous current per phase. This inverter board introduces a new modular concept where a separate dual-in-line module (DIM) is inserted into the board to configure it for a particular dsPIC DSC or MCU.

The motorBench Development Suite is a free GUI-based software development tool for FOC that accurately measures critical motor parameters, automatically tunes feedback control gains and generates source code by utilizing the motor control application framework (MCAF). The latest version, v2.45, includes a powerful new feature called zero-speed/maximum torque (ZS/MT), which enables designers to eliminate Hall or magnetic sensors while maximizing the torque output from the motor, from start-up and at low speeds. This feature can be used in pumps, power tools, e-Mobility and many other applications.

MPLAB Discover now contains many dsPIC DSC-based MATLAB Simulink models supporting various motor control algorithms and development boards. Microchip also provides free device blocks for Simulink that can be used to generate optimized code from models for dsPIC DSCs and other Microchip MCUs.

The growing number of dsPIC DSC-based motor control reference designs now includes an automotive cooling fan, low-voltage ceiling fan and a drone propeller controller. These reference designs shorten the time to market by providing a production-ready solution for various motor control applications. Typically, the board design files include schematics and a BOM, a board user’s guide and motor control source code that are available for download.
