Abstract
The input current harmonics of battery chargers affect harmfully on the overall power distribution network. They result in voltage distortion, heating transformers, reducing conduction capacity of cable, and affecting the interrupting capability of circuit breakers. In order to eliminate these problems, this paper presents an effective control scheme to remove input current harmonics of battery charger by controlling the current in phase with fundamental component of the grid voltage. The proposed control scheme not only achieves near-unity input power factor but also eliminates current harmonics in the battery charger regardless of the grid voltage disturbance. To validate performance of the proposed control scheme, both simulation and experiment are carried out.
