GaN Performance Advantage in Totem Pole PFC and LLC Converters

The webinar compares GaN E-HEMT with Silicon and SiC MOSFETs in a Power Supply Unit (PSU) with Bridgeless Totem Pole PFC and LLC resonant converter topologies. The presentation concludes that GaN E-HEMT solutions provide higher efficiency than SiC and 40 % higher power density than the conventional Si-based PSU design.
