摘要

提出了一种零电流软开关DC/DC电压变换输入型辅助逆变器方案，该辅助逆变器采用双段式变压器电路结构，前段为DC/DC开关电源电路，后段为三相逆变电路，系统采用零电流开关（ZCS）技术进行控制，实现了IGBT上电压和电流开关损耗最小化。试验结果验证了所提出的方案是可行的。

Abstract

An auxiliary inverter with zero-current soft switching DC/DC converter input was proposed. Two-stage transformer circuit structure was adopted, the front part of which was DC/DC converter, and the rear part of which was three-phase inverter circuit. Zero-current switching (ZCS) technology was used for control, so that switching loss of voltage and current on IGBTs was minimized. The experimental results proved the validity of the design.
