Shunt Active Power Filter and Its Application

Abstract

With the extensive application of high-power switching devices, the quality of electric power is growing problem seriously, which causes the current (voltage) distortion, producing a large number of harmonics. This paper introduces the principle, structure, device development and the characteristics of active filter, and its application in power system applications. Currently, The key is to further enhance the application of levels of active filter in the production practice, and to promote scientific research transfer into Industrial Molded Products quickly.
