摘要：

An accurately regulated multiple-output zero-voltage switching (ZVS) dc-dc converter is proposed. The converter is composed of three outputs altogether. The first and second outputs are regulated through the duty cycle control of two asymmetrical half bridge converters, while the third output is regulated through the phase shift of the two asymmetrical half bridge converters. The characteristic of this multiple-output dc-dc converter is analyzed and design process is investigated. ZVS is realized for all the main switches. Therefore this multiple-output dc-dc converter can operate with higher efficiency at higher switching frequency. The operation stages, ZVS condition and control detail are also presented. A 400 V input, 48 V/10 A, 5 V/20 A, 12 V/5 A outputs prototype is built to verify the design. The efficiency at rated input voltage full load is 93.36%.
