Abstract :
Current-fed quasi-Z-source inverter has many advantages when it is used in the vehicle motor drive: it has buck-boost function with single stage; it has regeneration capability; it protects the open circuit by itself. This paper is to demonstrate that this inverter also has fast transient response that it only needs several switching cycles to transfer from motoring mode to regeneration mode, which makes it very suitable to be used for HEV or EV motor drive. Theory analysis, simulation results and experimental results are all given to demonstrate it.
