전기자동차 실내 공조용 PTC Heater 구현을 위한 DC-DC 컨버터의 설계

초록

Recently, the market of Electric Vehicle(EV) is increasing more and more then before. Thus a new heater for EV is required . The PTC devices was used the heater for EV. In this paper, a simple DC-DC Converter is proposed for the PTC Heater for EV. The proposed circuit was optimally desired to decrease the stress of the power devices and reduce the current ripples. Finally, the proposed circuit is validated by various experiments.
