Abstract

A zero-voltage-switching (ZVS) pulse-width modulation (PWM) inverter that uses a parallel-resonant DC-link (PRDCL) circuit is examined. The PRDCL circuit provides zero-DC-link voltage periods for the inverter switchings and imposes minimum DC bus voltage stress on the PWM inverter. A simple circuit control scheme and the design formulas are presented. To confirm the analytical and simulation results of the circuit, a 50-W ZVS single-phase PWM inverter prototype using the proposed PRDCL circuit was fabricated and tested. The experimental results verify the proposed circuit and concept. The power device selections and device stress evaluations as well as a comparison of the ZVS inverter system with the conventional voltage source inverter are discussed.
