Abstract :
This paper deals with a fast dc voltage control strategy for a single-phase PWM rectifier. The PWM rectifier must control the active and reactive powers for regulating the dc voltage. Then, in this paper, a single-phase instantaneous active/reactive power theory (the ps-qs theory) is applied to a control strategy of a single-phase PWM rectifier. In addition, the stability of a single-phase PWM rectifier is analyzed, and a novel circuit topology and control strategy using a dc active filter is proposed. Some significant characteristics on our proposal are verified by using a 100 V/1.8 kVA experimental system.
