Improved Active Power Filter Performance by Instantaneous Power Theory
Ramisetti Umadevi,  Ch.Pavankumar
In this paper, a three-phase four-wire system connected a nonlinear load, dc/ac four leg voltage source converter to act as a four leg Active Power Filter (APF) using of instantaneous power theory is presented. The use of a four-leg voltage-source inverter allows the compensation of current harmonic components, as well as unbalanced current generated by single-phase nonlinear loads. The instantaneous power theory is applied to design the APF controller, which shows reliable performances. The MATLAB/SimpowerSystems tool has proved that the proposed control technique compensate the harmonic current drawn by nonlinear loads and controls the reactive power flow.
Keywords- Active Power Filter (APF), Instantaneous power theory, Nonlinear load, Voltage Source converter.
