Multi Point Clamped Converter for Fast Charging Applications in Electric Transportation

Abstract

In this paper, an off-board multi terminal dc charger with active input current shaping for level-3 electric vehicle (EV) charging applications is proposed. The proposed configuration is based on reduced switching state (RSS) multi-point clamped (MPC), three phase improved power factor converter (IPFC) and supplied by the standard ac grid. The topology has an advantage of reduced device count along with reduced maximum device stress. This will increase the speed of EV charging and elables the reduction of capital and maintenance costs of the charging facilities, enhancing further expansion of the ecofriendly transport. The validation of proposed topology is verified with simulation and a down scaled experimental setup. © 2019 IEEE.
