Abstract

This paper presents the design and analysis of an active energy recovery clamp circuit for an isolated full bridge dc-dc converter. The proposed energy recovery circuit is implemented on a 130V to 52V isolated dc-dc GaN converter. Initially an RCD circuit is used at the output rectifier to reduce the voltage spike from exceeding the desired value. Later, an active energy recovery circuit which includes a clamping diode, a clamping capacitor and a switching converter is used to recover the leakage energy and fed to the output of the main power converter. The efficiency of the converter with the proposed energy recovery circuit is compared with the RCD snubber and presented in this paper.
