LCL滤波的PWM整流器直接功率控制
Direct Power Control for PWM Rectifier with LCL Filter
A novel direct power control method for PWM rectifier with LCL filter is proposed.The instant power is calculated based on grid side currents and the damping power are constructed based on capacitor currents.Three-level hysteresis comparators and a new switching table are used to improve the control performance of reactive power.The simulation results show that the grid side currents have low harmonic distortions,the power factor is close to 1,and the resonance is suppressed effectively,which verify the validity of the proposed method.
