Study on a deadbeat control scheme for three-phase four-leg shunt active power filter

Rui Zhou

Abstract

Based on the study of four-leg shunt active power filter(APF),harmonic detection method for three-phase four-wire system and the control strategy for APF are researched respectively.To calculate the instruction current,the ip-iq harmonic current detection method based on instantaneous reactive power theory is adopted.The paper also discusses the principle of the deadbeat control scheme in detail and derives the deadbeat control model theoretically.The principle and realization steps of 3-dimension SVPWM and the predictive method for compensation currents are researched as well.Experiments verify the feasibility of the deadbeat control system.Advantages and the existing problems of the deadbeat control system are summarized conclusively.
