2.4 High Side Bias Supply Challenges and Solutions in Halfbridge Gate Drivers

Details

Date: October 9, 2017

This presentation discusses challenges associated with high side bias in half-bridge gate driver ICs and also provides solutions to those challenges. This presentation shows what are the challenges with bootstrap biasing technique, how bootstrap diode forward reverse current affects the performance of the gate driver IC, what are the effects of value of bootstrap capacitor, and what are the effects of switching frequency. Presentation also discusses how different power supply topologies pose different challenges to half bridge gate driver IC and its bias supply.
