The mathematical model is derived from a three phase three wire rectifier.A vector de-coupling control scheme is used and the relative voltage loop and current loop controllers are designed respectively.Then,in order to suppress the disturbance of voltage ripples to the voltage loop control-ler,a notch filter is designed to eliminate the harmonic component from the dc side voltage feedback. The method can realize the ideal filtering effect besides good system stability.The simulation results verify the feasibility of the notch filter in application to the three phase three wire rectifier.
