abstract
For current-source-rectifier (CSR)-based systems, sinusoidal supply current and unity displacement power factor in the utility are achieved through either a pulsewidth-modulation CSR or a phase-controlled rectifier in conjunction with an active filter. This paper investigates theoretical studies and analyses for the two topologies from the standpoint of converter kilovoltampere rating and switch rating. 2006 IEEE.
