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.
