A power-factor-correction (PFC) rectifier using a novel circuit topology and its control method was developed and tested. To reduce both conduction and switching losses, the proposed circuit is based on a bridgeless PFC boost rectifier with a zero-voltage-switching (ZVS) function. To achieve ZVS, the proposed circuit topology employs a simple auxiliary(More)
A bi-directional isolated DC-DC converter using a novel circuit topology and its control method are described. The proposed circuit is based on a voltage-fed full-bridge circuit on the high-voltage side and a current-fed full-bridge circuit with an active clamp circuit on the low-voltage side. In order to make use of only MOSFETs with slow body diodes in(More)
