A clamping current control technique, based on one cycle control OCC

Abstract

This paper proposes a clamping phase technique that results in power factor control at the input of a controlled rectifier by means of a current control based on One Cycle Control (OCC) technique. It minimizes phase interference, fixes operation frequency as well as improves phase coordination. Control simplicity and voltage input sensor elimination is the feature of the proposed control. Theoretical background of the clamping phase technique as well as of OCC principle has been reviewed and analyzed. Simulated results confirm the proposed technique.
