Conventional three-phase PWM rectifier requires multiplier,dq coordinate transformation and network side voltage detection,and control algorithm is complex.In this paper,one cycle controlled PWM rectifier can simplify the design.This paper deduces the control principle of the one-cycle controlled three-phase PWM rectifier,proves its equivalent relation with the SPWM,studies the stability of the system and proposes the design method of parameters in control aspect.A 10 kW three-phase PWM rectifier simulation model is set up,and compared to the traditional SPWM control method this model has a faster dynamic response,simpler control method,higher stability and realizes the unit power factor.Finally feasibility and efficiency of one-cycle controlled three-phase PWM rectifier are validated through experiment.
