To manage and regulate power with both efficiency and finesse, electronics designers turn to Pulse Width Modulation (PWM). This powerful technique rapidly toggles a signal between on and off, adjusting the “on” time — known as the duty cycle — to control the effective average power delivered to a device. Whether tempering brightness in LEDs, […]

APEC 2023 round-up
The Applied Power Electronics Conference (APEC) has grown over the course of a few decades to be the leading conference in North America for power electronics professionals. This past month, March 19th to the 23rd, in Orlando, APEC returned to share the latest trends, technologies, and opportunities in power electronics with industry and academia alike. […]
APEC seminar shows the importance of power integrity
Three top power-integrity engineers explain why you must consider the complete power system. Looking at just the power supply is not nearly enough. “There’s a hard divide between power integrity and power electronics,” said Picotest’s Steve Sandler. What is he talking about, you might ask? Sandler, along with Keysight’s Heidi Barnes and Signal Edge Solutions’ […]
APEC 2022 professional education seminars cover range of key topics
The annual Applied Power Electronics Conference (APEC 2022) announces this year’s slate of Professional Education Seminars. Delivered by electronics professionals and academics and covering a range of topics, the seminars are designed to provide practicing power electronics engineers a deep dive into subjects critical to their design activities. Professional Education Seminars are divided into five […]
Talk of EV fires still smolders
Leland Teschler • Executive Editor lteschler@wtwhmedia.com On Twitter @ DW_LeeTeschler The latest figures from the National Fire Protection Association show that only about 20% of all vehicle fires arise from problems in the vehicle electrical system—most fires have something to do with the fuel system. Seeing as electric vehicles will do away with problematic petrol, […]
Isolated gate drivers feature low latency, high switching speeds
Silicon Labs introduces new Si823Hx/825xx isolated gate drivers offering an uncontested combination of faster and safer switching, low latency, and high noise immunity capabilities that enable a compact PCB design for closer placement of the device to power transistors. New advancements in these gate drivers help power converter designers meet or exceed increasing energy efficiency standards […]
Comparing piezoelectric, electrostatic and electromagnetic device applications
By Margaret Bezerko, President of SensComp When it comes to electronic design, function dictates framework. While piezoelectric, electrostatic, and electromagnetic devices offer distinct benefits, each comes with specific drawbacks and best-fit applications. In this piece, we’ll examine each system with a quick analysis of operating mechanisms, potential pain points, and ideal use cases for current […]
