Abstract

In this paper, a new unity power factor isolated three-phase buck rectifier is presented. Based on the Scott transformer, this rectifier is simple and it has the capability to obtain low output voltage. Besides, it protects against short circuit and it needs no auxiliary circuit for inrush current. Using only two active switches, it is able to generate symmetrical currents in the line and output voltage regulated. The modulation is used conventional SPWM. The control has only one voltage control loop. Theoretical analysis, design procedure, complete simulation results with closed loop operation are given, as well as results of an experimental verification.
