چکیده:

This paper proposes a new topology for active power filter (APF). In the proposed topology, the employment of an indirect matrix converter (IMC) as a part of shunt active filterhas been investigated. Using the proposed IMC based APF, the dc link capacitor can be removed and also the average of dclink voltage can decrease in 1.5 times of the peak of source voltage. Furthermore, in this paper a new control method based on instantaneous power theory or P-Q theory and predictive current control for proposed APF is presented. In the proposed control method, there is no need to control the voltage of dc linkand the average of voltage is always constant. Using PWM based control strategy, the injected harmonics will be producedaround and more than switching frequency and the size of filters will be decreased. The simulation results obtained from PSCAD/EMTDC software confirm the validation of the proposed topology advantages and its control method.
