PROBLEM TO BE SOLVED: To provide a diode rectifying circuit which can reduce the harmonic components generated in an input current at the diode rectifying circuit and expressed by 12n±1-th order, where n=1, 2, 3,...} and whose configuration can be made compact. SOLUTION: In a diode rectifier 4 and a diode rectifier 4' to which voltages having a phase difference of 30 deg. are input from a three-phase AC power supply 1, a voltage whose frequency is six times the frequency of the voltages which are input to the diode rectifiers is added to the output voltage of the diode rectifier on one side, and a voltage whose phase is opposite to that of the voltage at the six times frequency is added to the output voltage of the diode rectifier on the other side. |
