| Abstract |
An active snubber for soft-switching is proposed. A half-bridge and a small inductor are added to a single-phase 3.6 kW totem-pole boost PFC converter, implemented with GaN E-HEMTs. It enables CCM operation with efficiencies above 98\% at 250 kHz, therefore high power density. Operation, simulations, and experimental results are presented. |
