Implement of A High Current Three Phase Double Star Rectifier

In this paper a double star rectifier with interphase connection that know as ANSI 45 has been studied. To achieve high direct current, rectifiers will be paralleled, which it know as multi-phase rectifiers. Harmonics transferred to the grid are reduced by multi-phase rectifiers. Double star rectifiers are used for low voltage and high direct current in the industry applications. Also, to overcome the saturation state of the transformer, a reactor is used at the common point of the star. In this rectifier, the output injected current will be controlled. MATLAB/Simulink software is used to simulate this rectifier. Then a 6 kA, 180 kW double star rectifier is designed and made.
