Abstract :
This paper presents a new topology of a three phase rectifier operating in the discontinuous conduction mode (DCM). It is based on the buck-boost converter and has the step-up and step-down characteristics of output voltage. The rectifier draws sinusoidal ac current from ac line with unity power factor, and needs only one switch and constant duty cycle of PWM control. The dynamic and steady equations of converter are analyzed. The results of the theoretical analysis are verified by digital simulation and the experiment results of laboratory prototype.
