The configuration and principle of a hybrid filter system with series active filter is analyzed. According to the feature of single phase system, a harmonic current detecting method and a pulse width modulation method are presented. Because of the use of zero vector, the wave controlling possesses higher precision. The experimental results of single phase hybrid filter system based on SAPF are given. It is shown that in hybrid filter system the SAPF can be used as an isolator of harmonic current between the source and load. Thus, the filtering characteristics of passive power filter (PPF) can be remarkably improved.
