Soft-Switching DC-DC Converter with SiC Full-Bridge Rectifier

Abstract

The paper presents a full-bridge dc-dc converter with half-controlled rectifier and non-dissipative turn-off snubber. The topology and control algorithm is described together with operation in time intervals. The operation of the converter is verified by measurements on the laboratory model of the converter. The SiC transistors and diodes are used for the secondary side high-frequency rectifier.
