A novel simplified space-vector modulated control scheme for three-phase switch-mode rectifier

A novel simplified control scheme for three-phase switch-mode rectifier is proposed in this paper. The proposed control scheme is based upon a load-conductance rectifier controller, in which reference current signals are obtained. The goal to follow the reference current is converted to follow a reference voltage. A simplified control scheme utilizing space-vector modulation is developed to calculate the duty ratio required to synthesize the reference voltage. The proposed scheme has the advantage of space-vector modulation with fast dynamic response, and is simple enough to be implemented in a low-cost microprocessor.
