Abstract

This paper presents performance evaluations in steady and transient-states of quasi-resonant commutated bridge arm link three phase PFC rectifier with instantaneous power feedback and DC output voltage regulation loops. This three phase PFC rectifier topology is based upon digitally-modulated sinewave space vector processing, which can operate under a principle of ZVS-PWM transition due to auxiliary quasi-resonant commutation circuit incorporated into each three phase bridge arm. In the first place, a practical design of auxiliary resonant commutation circuit with current source type load model is graphically described on the basis of its state variable analysis. In the second place, the digital control system of three phase voltage-fed soft-switched PWM converter suitable and acceptable for high power utility applications is implemented on the synchronous rotating d-q coordinate axis. Finally, a novel prototype of this three phase PFC rectifier operating at soft-switching PWM strategy is evaluated as compared with hard switching PWM three phase PFC rectifier in terms of computer-aided simulation results.
