Abstract :
In this paper, an improved phase and amplitude control method for a PWM AC to DC voltage type power converter which introduces state feedback control of an LC filter is presented. The feedback of the state variables of the LC filter connected to the AC side of the power converter compensates a current offset of the supply current and also eliminates the oscillations of the DC output current and voltage waveforms during transients. Computer simulation and experimental results of the proposed system are presented to confirm the effectiveness of the control method
