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