Diode clamping overcurrent protection method applicable to topology morphing technique in LLC resonant converter for DC electric vehicle chargerDC 전기차 충전기를 위한 LLC공진 컨버터의 토폴로지 몰핑기법에 사용가능한 다이오드 클램핑 과전류 보호방법
Recently, EVs (Electric Vehicles) increased their pack voltage from 400V to 800V. It has shortened the charging time but, DC fast chargers now need to consider both 400V and 800V systems. Such broad output voltage range decreases the efficiency of the chargers. The topology morphing technique can be used in this case to have advantage in the efficiency. However, there’s not enough research about protection method for the topology morphing technique. Therefore, this paper introduces diode clamping overcurrent protection method that can be applied to topology morphing LLC resonant converter for DC fast EV chargers’ case.
