ABSTRACT:
A harmonic and pulsation reducing circuit used in multiplex polyphase rectifier circuits such as a multiplex polyphase rectifier, a branch reactor, an external commutated invertor, etc. which is characterized in that a rectifier circuit to rectify the induced voltage of a secondary winding provided at interphase reactors interposed between other plural rectifier circuits is connected between the center of the interphase reactors and loads or a DC power source so that the rectified voltage may be superposed on the DC output voltage of the said plural rectifier circuits or the other DC power source.
