Control strategy for high power active power filter

The paper is talked about a high power active power filter. The main circuit topology adopts a three-phase three-line voltage source converter,which is constituted by three H-bridges. The delta connection H-bridge topology has a good ability to compensate unbalanced load and fulfills the requirements of energy compensation device for use in high power applications. This paper presents a compound control methods, which can achieve the ideal control effect of the harmonic current and reactive current of grid.
