MOSFET Switching Losses - A Deep Dive


Thu, September 27th, 2018 from 1:00 - 2:00 PM EDT

The MOSFET switching losses for a typical synchronous buck converter were described in a previous webinar which also covered efficiency of the power train in general: 

Modeling Switching Losses and Efficiency

In this one-hour webinar, we focus on the losses of the MOSFETs, exploring and quantifying the losses due to conduction, reverse recovery and the turn-on and off losses due to the non-linear capacitance of the switches. Comparisons between a SPICE model and a SIMPLIS model will be covered with example circuits for each. Finally, we present a DVM testplan which automates testing the different circuits and plots the losses on summary graphs.
