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.
