HARMONIC WAVE AND PULSATION REDUCING CIRCUIT IN MULTIPLEX POLYPHASE RECTIFIER OR INVERTER WITH INTERPHASE REACTOR

摘要

A circuit for reducing harmonics in the current on AC side and the pulsation in the voltage on DC side in a multiplex polyphase rectifying circuit or an inverter, each having an interphase reactor and plural rectifying circuits, wherein a plural number of taps is provided either on said interphase reactor or on the secondary windings thereof which is directly connected with the central point of the interphase reactor on the central point thereof, and the taps are connected to the DC circuit respectively via rectifying elements.
