Part 1 of this FAQ set the stage for a rudimentary understanding of FOC (field-oriented control) but did not delve into the math-heavy details. Part 2 now looks at some implementations, again without the underlying math. Q: If a designer wants to implement FOC, does he or she have to pull together all the hardware […]

Heat sinks, Part 1: Thermal principles
A heat sink is a non-electronic, passive mechanical component that has a vital role in the reliability and performance of ICs, PC boards, modules, chassis, and more. Heat sinks often don’t get much attention, at least not in the early stages of a design. This FAQ will look at the basic thermal principles of these […]
Power Electronics Top Talks in November on EDABoard.com forums
Peer-to-peer, engineer-to-engineer questions and answers from the EDABoard.com engineering community around power electronics. Click the “Read more” link and follow the entire conversation and maybe add your two cents by logging in to EDAboard.com Dell power supply – I got this PSU from one of my colleagues and did a quick inspection for the faults in […]
electronica 2018: Get smart, Get small, Get integrated
I thought I heard about 100 different languages spoken as I crisscrossed 17 halls over four days in Munich at electronica 2018 with an average of eight miles a day of walking. I was wrong. It was closer to 180 languages. Tens of thousands of attendees were laser-focused on simplifying design and integrating devices and […]
Blood oxygen meters, Part 1: Background and principles
It is now trivial and non-invasive to measure blood-oxygen saturation SpO2, thanks to LEDs, algorithms, and ICs for pulse oximetry — and it’s a very long way from having to draw blood and send it out for assessment. Just a few decades ago, determining the vital medical parameter known as blood oxygen level — formally […]
Low-power single-chip temperature sensor performs like RTDs
Texas =Instruments has introduced a new temperature sensor family that offers ±0.1°C accuracy across a wide temperature range and helps simplify system design for industrial and medical applications. The TMP117 is the first single-chip temperature sensor to offer similar performance to platinum resistance temperature detectors (RTDs) while significantly reducing design complexity and power consumption, and […]
How telematics is evolving with the connected car
The embedded systems that control vehicle tracking grow more sophisticated by the day. Hope Bovenzi, Texas Instruments Inc. THE phrase “car of the future” often invokes thoughts about autonomous driving. But it is fair to also consider what it will be like as a passenger once our driving habits change. With free hands and relaxed […]
Grid links get more compact thanks to gallium nitride
Serkan Dusmez from Texas Instruments recently recorded a short video with us on a gallium-nitride based grid link. It is a three-phase, three level bidirectional grid tight inverter developed jointly by Texas Instruments and Siemens. It includes 600-V GaN TI drivers that incorporate smart features like over voltage protection and over temperature protection in a […]
TI SiC MOSFET gate drivers make for smaller inverters
Nagarajan Sridhar from Texas Instruments recently filmed a video with us covering a demo of a solar panel inverter that uses Texas Instruments silicon carbide MOSFET gate drivers. He points out that the switching frequency of silicon carbide far exceeds the capability of that available through silicon IGBTs or MOSFETs. The demo circuit is a […]
Controllers for micromirror imaging deliver micron-to-sub-millimeter accuracy for 3D printers and portable 3D scanners
Texas Instruments today announced new DLP Pico controllers that deliver advanced light control capabilities in smaller form factors for mass-market 3D scanners and 3D printers. DLPC347x controllers offer the micron-to-sub-millimeter resolution typically found in high-performance, industrial-grade applications in a smaller form factor for desktop 3D printers and portable 3D scanners. Developers can pair the new […]
