A multiplicator ZCS turn on boost converter with high-efficiency and high-voltage-gain

Abstract

This paper presents a multiplicator ZCS turn on boost converter with high-efficiency and high-voltage-gain. A resonant multiplicator structure combined with two-phase technique is provided. Based on this structure, the problem of switches turn-on loss and inductor current ripple is minimized. The voltage resonant multiplicator also shows a good scalability. And the presented prototype is well adapted for multiphase dc-dc converters. The converter is tested for an application requiring the output power of 100W∼500W, operating with 12V input voltage and 220V output voltage. The measured peak efficiency equals to 95.4% with the gain of 18.333.
