A study on the Push-Pull type high frequency resonant inverter connected boost converter

부스터 컨버터가 결합된 Push-Pull형 고주파 공진인버터에 관한 연구

This paper describes a Push-Pull type high frequency resonant inverter composed of consolidation of boost converter circuit and resonant inverter circuit. By using a boost converter circuit, the proposed inverter can obtain a twice input voltage of resonant circuit and reduce a secondary turn ratios. also, by using both switching device of boost-converter and resonant circuit, the number of switching device can be reduced by half, the analysis of the proposed circuit was generally described by using normalized parameter and operating characteristics have been evaluated as to switching frequency and parameters. In the future, this proposed inverter shows that is can be practically used as a power source system for the lighting equipment of discharge lamp, induction heating applications.
