Abstract: This paper proposes a new α×β control method modified from traditional SPWM in a basic bi-directional DC-DC Z-source converter topology which are expected to be applied in Electric Vehicle's charging and discharging. The converter can both boost and reduce the voltage in the operation of battery's discharging to the grid with this closed loop control scheme. It can also achieve charging the battery from the grid with special control of switches. PID control is adopted to improve the overall performance. Simulation results in Matlab Simulink proved the effectiveness of this control method applied on this bi-directional topology.
