Abstract :
A high power factor rectifier circuit using a higher switching frequency generally has an LC filter installed at the AC side in order to eliminate the switching ripple. The method to determine the optimum values of L and C are not established yet. We presented an optimum LC filter for a single-phase boost type rectifier with a single switching device. This paper deals with a design method for the LC filter in a three-phase boost type rectifier widely used. The following characteristics are estimated by changing LC parameters; a total harmonic distortion of an input current, a phase lag of the input current, a harmonic content factor near a switching frequency and a ripple factor of a filter capacitor voltage. The appropriate values of the LC filter are determined
