초록
A Hight Efficiency Quasi-Parallel Resonant DC-Link Inverter which shows highly improved PWM capability, low loss characteristic and low voltage stress is presented. A method to minimize freewheeling interval, which is able to largely decrease DC-link operation losses and to steadily guarantee soft switching in the wide operation region is proposed. Analysis and simple experiments were performed to verify validity of the proposed inverter topology.
