A Study on teh Improvement of Resonant Inverter

공진형 인버터의 개성에 관한 연구

In this paper the conventional resonant inverters are compared and a novel parallel resonant dc pulse inverter for high performance motor drive system is proposed. The design method and related equations for the novel resonant inverter are derived. Also, a current controller for the resonant inverter is proposed and compared with PI current controller of the conventional PWM inverter by analog simulation. The novel resonant inverter and the current controller are implemented to verify the suggested design principles. The analog simulation and the experimental results shown the satisfactory operation of the proposed inverter and the controller.
