A performance comparison of PWM rectifiers and synchronous link converters

PWM AC/DC power converters have been shown to be superior to thyristor phase-controlled rectifiers in terms of power factor and input current/output voltage harmonics. This paper presents a systematic comparison of the two topologies, the current-source topology and the voltage-source topology, from the point of view of power converter and switch kVA ratings, filtering requirements, power factor, operating regions, and control aspects.<
