Three-phase voltage source PWM rectifier based on space-vector algorithm and one-cycle control

Based on the above literature, through studying the three phase voltage PWM Rectifier of onecycle and deriving the control law, derive a spacevector mode controller of one-cycle, combining the space vector control method and one-cycle, dividing the grid voltage in six intervals according tothe 1 INTRODUCTION In the electric vehicle charging field, with the advantages of the grid side current harmonic, the low unit power factor, energy bidirectional flow and constant DC voltage, the PWM rectifier has been gradually getting attention; this is especially in the research of V2G, V2H, where it has been used in the research of application. Direct Current Control with the advantages of fast dynamic response is widely used in many control methods [1]. At present, the methods of direct current control are: average current, hysteresis current, forecast current and so on; these control methods require using of multipliers to produce the command current signal. The three-phase PWM rectifier is a system of multi-input multioutput and time-varying strongly coupled-so nonlinear distortion generated by the multipliers will cause system instability and harmonic distortion of input current [2].
