Improved analysis for the benchmark system of an active power filter

This paper represents the estimation method based on a benchmark system for control of active power filter (APF). The active power filter consists of a three-phase voltage source converter operating under pulse-width modulation. The method allows the harmonic prediction is employed to allow accurate harmonic compensation despite controller latencies. The current control is done in time domain. A three-phase active power filter is simulated with Matlab to demonstrate the performance of the proposed method. The results clearly validate the accuracy of the simulation model.
