Abstract :
In this paper, a novel power converter for electric vehicles (EVs) is proposed. The proposed converter has a Z-source inverter which drives an ac motor, and performs as a current-fed Z-source dc-dc converter against reverse power flow. Thus, the proposed circuit does not need a bi-directional buck-boost dc-dc converter. The operation of the proposed converter was simulated by MATLAB SIMULINK and tested by circuit experiments for each operation as a Z-source inverter and a current-fed Z-source dc-dc converter.
