A Combined ZVS Converter with Naturally Sharing Input-Current and High Voltage Gain

Abstract

A new combined ZVS converter topology is studied in this paper to meet the demands of high power density of power supplies. By interleaving two-phase-shifted full-bridge converter modules, the presented converter has many advantages such as natural sharing input-current, high voltage gain, low voltage stress of the transformer second-side diodes, small volume of input and output filters and so on. The simulated and experimental results show that the converter is suitable for high power and/or high voltage applications
