Abstract

It is desirable that the rectifier that is an ac-to-dc converter, have the characteristics of fast response and the wide range of the output voltage control, and the sinusoidal source current waveform. In this paper, a step up/down output voltage PWM-controlled rectifier is proposed. The features of the proposed rectifier are as follows: 1) The calculation of pulsewidth is based on the geometrical technique and the source current can be in-phase with the source voltage. 2) The output voltage is controlled from about zero to more than the maximum value of the source voltage.
