Study on the control method and operation characteristics of BUCK-BOOST Converter for ZVS and ZCS

ZVS과 ZCS을 이용한 BUCK-BOOST콘버어터의 제어방식과 동작특성에 관한 연구

In this paper, for a constant switching frequency, the configuration and the control strategy of the resonant buck-boost type converter are proposed by the combination of zero voltage switching(ZVS) and zero current switching(ZCS) with PWM method. Also, in the configuration of power control circuit, transformer is not used in the viewpoint of economy. And the circuit has fewer power switching elements than a general resonant power converter, simulation results and experiments make show the advantages mentioned.
