This paper deals with the steady state performance of a novel controlled rectifier, using an IGBT A.C controller on the primary side of the input transformer, while a center tapped secondary and normal diodes are used for rectification. Such a rectifier is suitable for low voltage high current applications. The IGBTs are controlled such that this type of controlled rectifier has a better displacement power factor because the line current drawn is symmetrical in relation to the peak of the a.c input voltage. Thus the fundamental component of the line current drawn will be in phase with the line voltage. Theoretically expected and experimentally obtained waveforms of currents and voltages are presented.
