Abstract
In this paper, a new low cost three-phase AC-DC high power/low harmonic controlled rectifier is presented. The circuit consists of a three-phase diode bridge rectifier followed by a boost stage containing only one switch and one boost-inductor; the proposed converter is used to automatically draw sinusoidal input current waveforms, with high efficiency. This is achieved with discontinuous input voltage to the rectifier and with a discontinuous inductor current mode of operation of the boost converter. Thus, the input diode rectifier operates in zero-voltage and zero-current switching conditions, avoiding reverse recovery problems. This paper describes the proposed circuit and its analysis, design and performance. This circuit is compared with two other schemes used for current harmonic reduction to satisfy the IEEE 519 standard in three-phase utility interface. The limitations of the proposed converter are discussed. >
