Abstract：Hybrid electric vehicles(HEV) which drove by car inverter has been paid more attention. This paper propose an AC/DC hybrid multilevel converter that is composed of cascaded H-bridge, matrix converter and medium frequency transformer due to the existing converters have the problems as: dynamic voltage-sharing of each battery module, power density, service life, safety and so on. The proposed topology can achieve independent control of AC/DC input mode and be compatible with battery and generator power supply and Plug-in mode. The use of medium frequency transformer and matrix converter decrease the weight and volume of the system, thus achieve the operation in 4-quadrant with high power density. Without large-scale series of battery groups, the proposed extend the service life of the battery, improve the reliability and power utilization. The validity of the proposed method has been verified by simulation and experiments.
