PROJECT TITLE :
Dynamic Control and Analysis of DC-Capacitor Voltage Fluctuations in Three-Phase Active Power Filters
This paper proposes a new management technique of 3-section active power filters for reducing the dc capacitor voltage fluctuations in transient load amendment. The proposed management method introduces a new k-step compensator, which maintains the mean active power flowing into the dc capacitor at zero every one/(k-one) ac line amount. Thus, the compensator will suppress the transient voltage fluctuations across the dc capacitor even when a quick load amendment happens. This paper theoretically reveals the link between the step number k and also the reduction impact of the dc voltage fluctuations. The experimental setup introducing the proposed seven-step compensator exhibits a good suppression impact of the dc voltage fluctuations and makes it doable to cut back the specified capacitance value of the dc capacitor by a factor of seven.
