Description
The Evaluation Board for a bridgeless totem-pole Power-Factor-Correction (PFC) circuit,using Transphorm GaN power HEMTs, is described in this application note. In this board, byusing a diode-free GaN power HEMT bridge with low reverse-recovery charge, very-highefficiencysingle-phase AC-DC conversion is realized. In this circuit, the performance andefficiency improvement, achieved by use of the GaN HEMTs in the fast-switching leg of thecircuit, is further enhanced by the use of low resistance MOSFETs in the slow-switching leg
