Design of Main Circuit and Analysis of Active Power Filter

Article Preview

Abstract:

With the use of power electronic equipments and increasing nonlinear loads, the problems of quality of power supply becomes serious. Different kinds of loads need different active power filter (APF). Performance of APF depends on the design of main circuit. In this paper, the principle of APF and many kinds of structure of main circuit are presented. Multilevel, injection circuit and multiplicity are analyzed. A combined controller, the combination of PI controller and fuzzy controller, is applied to voltage control of DC side.
