Software Realization of a Novel Parallel Resonant DC Link Inverter Control Strategy

To solve the problems of traditional hard switching inverter, a novel parallel resonant DC link inverter topology is proposed, the inverter´s configuration and working principle is expounded. Through analyzing generating mechanism of soft switching zero voltage condition , it puts forward the matching strategy between inverter and resonant auxiliary link to make the inverter switches achieve ZVS, it discusses the key problem that how to combine soft-switching technology with PWM technology, and the resonant matching software controller is designed. The experiments results confirm the method that realize resonant matching by software controller is practical and feasible.
