This paper presents a detailed operation analysis, controller design, and realization of high-power, bidirectional quasi-Z-source inverter (BQ-ZSI) for electric vehicle applications. The circuit analysis shows that with switch in the network, performance under small inductance low power factor can be improved. Based on signal model BQ-ZSI is derived, which indicates prone to oscillate when there disturbance dc input voltage. Therefore, dedicated voltage feed-forward compensation designed...
