Abstract

As the existing contactless power transfer system(CPTS) is adopting the principle of contactless transformer enables to supply power in contactless way using RFID(radio frequency identification)/ID communication method between primary and secondary sides of contactless transformer and detect the alien load. Such CPTS requires the circuit that generates ID in addition, and the ID identification and control generated from the secondary side is performed at the primary side, which cuases complexity of the circuit. Therefore, this study suggested the CPTS using voltage phase, and In order to verify the validity of this study, 3[W] class CPTS shall be designed, and the simulation and test of CPTS using current and voltage phases shall be carried out.

기존의 무접점 전원공급 시스템은 비접촉 변압기의 1, 2차측 간 RFID/ID 통신 방식을 이용하여 무접점으로 전원을 공급하고, 이물질을 감지한다. 이러한 시스템은 ID 신호를 발생시켜주는 회로가 추가 되어야 하고, 2차측에서 발생한 ID 신호의 인식과 제어는 1차측에서 수행하기 때문에 회로의 복잡성이 야기된다. 따라서 본 논문에서는 전압위상을 이용한 무접점 전원공급 시스템을 제안하고, 타당성을 증명하기 위하여 3[W]급 무접점 전원공급 장치를 설계하고, 시뮬레이션 및 실험을 수행하였다.
