Software realization of a novel parallel resonant DC link inverter control strategy

摘要

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.
