Three-phase rectifying circuit with power factor correction and harmonic suppressing circuit

The utility model discloses a three-phase rectifying circuit with a power factor correction and harmonic suppressing circuit. A three-phase reactor, three electric inductances and three capacitors are added in the circuit, wherein, the three electric inductances are separately connected with a three-phase bus bar in series, and output terminals of the electric inductances are used as input terminals of the three phases of the three-phase reactor, and output terminals of the three-phase reactor are connected between two filtering capacitances through a regulating electric inductance. One end of the three capacitors are connected with each other as a common end, and the other ends of the three capacitors are separately connected to the three-phase bus bar. The utility model effectively suppresses the harmonic, and makes the power factor compensation reach to more than 95%.
