Figure 1: Power stage of the flyback converter (simplified)

Eleazar Falco, FAE, Würth Elektronik eiSos / Editor, Gerhard Stelzer

Isolated flyback converters often use optocouplers in the feedback loop to regulate the output voltage. As part of the compensation circuit, its parameters such as CTR influence the control loop and must be taken into account in the flyback converter design. The flyback converter is an isolated switching power

BEVs Have a Weight Problem That Can’t Be Solved with Traditional Approaches

Noa Margolin, R&D Engineer, Vicor Corporation

Battery-electric vehicles (BEVs) have a serious weight problem and not the type Weight Watchers® can fix. Many BEVs are as much as 33% heavier than their internal combustion engine vehicle (ICE) counterparts. The chair of the National Transportation Safety Board noted “The Ford F-150 Lightning is betwee

Multi-Dimensional MOSFET Modeling With Interactive Datasheets

Stein Nesbakk, Nexperia

Datasheets are often long and cumbersome, meaning locating and interpreting the required information is not always trivial. Furthermore, the meaning of the listed parameters is rarely explained in the datasheets, and even the slight differences in how they are interpreted can be critical for how a device behaves in
