Three-phase voltage PWM rectifier can work with sinusoidal current and can reach in unit power factor state for the whole power range, so it is an environmentally friendly convertor. In this paper, the working principle of three-phase voltage PWM rectifier and the design method of voltage-current double closed-loop controller based on the direct current control (DPC) are introduced in detail. Finally, the simulation and experimentation result validate the feasibility of the design.
