Abstract
A novel digital control algorithms are developed for an active power filter (APF) using a pulse-width modulated (PWM) rectifier with current link. A main control algorithm compensating both the reactive power and harmonic currents with fast dynamic response is derived through a vector approach. A space vector modulation technique is developed for the PWM rectifier in order to generate the desired current vector of the APF. The system generates no acoustic noise and it is implemented with a minimal control hardware structure using the Intel 80196 single-chip microcomputer. Experimental results show that the proposed scheme gives good dynamic and static performance for the APF system.
