SiC MOSFETs in hard-switched half-bridges


Silicon carbide (SiC) MOSFETs are making major inroads into solar inverters. Engineers are keen to achieve high efficiency across the entire load range. SiC MOSFETs' low on-state resistance and low switching losses support those efforts, especially when the focus is on achieving high efficiency at light loads.

The intrinsic body diode is a very rugged component that enables engineers to install SiC MOSFETs in hard-switched, totem-pole configurations that use synchronous rectification to achieve highest efficiency. But latest-generation SiC MOSFETs have their limitations. This webinar zooms in for a closer look at these drawbacks and puts forward solutions to resolve the issues at hand.

Agenda:

  • Why SiC MOSFETs are becoming popular in solar inverters?
  • Benefits and drawbacks depicted on a case study
  • How to overcome the limitations
  • Reliability constraints
