【Abstract】 In this paper, a mathematical model of three-phase voltage source converter was first derived in the stationary and synchronous reference frames. Secondly, modeled the three-phase four-active-switch voltage source converter and the control law to handle the effect of unbalanced input voltage was analyzed. Then, a load current feed-forward control was used to improve the transient performance of three-phase voltage source converter. Finally, the simulation results were given.更多还原
