In this thesis,we mainly investigate the resonant soft switching PWM inverter.The main contents are as follows:1. Through analysis of the DC-Rail resonant soft swithing inverter and ZVT(ZCT)-PWM technique , we advance the solution to resolve the question-how to apply PWM technique to control DC-Rail resonant soft swithing inverter is resonant transition technique.2. we present a novel de-rail parallel resonant zero voltage transition three-phase PWM voltage-source inverter which is based on resonant zero voltage (zero current) transition technique; at the same time it's efficiency analysis and simulation result are presented.3. To realize the controllation of system we apply 8XC196MC to provide SPWM signal ,at the same time we use assistant circuit to control those assistant switch.In final section the problem of the inverter is concluded and the new method to realize the controllation of system is presented.In the end the prospective research direction is discussed.
