Simple Series-Compensated Single Phase Active Power Filter

Abstract

In this paper, a circuit configuration and a principle of a new type series-compensated single -phase active power filter are described.In comparison with a conventional circuit , a filter inductance became unnecessary and a new method of a feedback-control for the output voltage was applied to reduce the voltage distortion .Propriety of this circuit was confirmed by simulation results.As a capability equivalent to a conventional circuit was maintained , the size became small.
