Abstract

A DC-DC converter of 10 KW capacity for converting 144 V DC voltage available as a battery supply to 600 V DC for battery backup drive is presented in this paper. The converter uses full bridge inverter - transformer -rectifier scheme to provide galvanic isolation between input and output and uses IGBTs to switch at 6 KHZ. The simulation results are shown and discussed. In this paper, a phase shifted control scheme is compared with conventional control scheme applied to an isolated dc-dc converter configuration with full-bridge inverter at the primary side and a fast recovery rectification method at the secondary side of the transformers. The proposed scheme is illustrated and experimentally verified by a 600 V, 10 kW prototype.
