Abstract
The proposed system consists of an LC passive filter connected in series with three-phase active power filter. The passive filter is tuned to 13th order harmonic frequency. Major portion of harmonic current generated by nonlinear load is absorbs by passive filter, and active filter is used to improve filtering performance of the system by providing compensation for host of other higher order harmonics. Requirement of dc-link voltage of the active filter is less in the presented scheme as compared to that of standard voltage source active power filter without any other passive filtering component. This resulted in significant reduction in cost and power rating of active power filter. Analysis and design of various components of active filter are presented. Simulation analysis is carried out using instantaneous active-reactive power (P-Q) theory. Simulation results verify circuit configuration and filtering performance of the proposed topology. This system can be an attractive solution for effective harmonic filtering.
