Output feedback non-linear harmonic control of an industrial electric vehicle battery charger

Abstract : For complying with power distributor regulation, the electric car chargers have to address the line current harmonic mitigation problem. The conventional solution is a proportional integral controller on the rectified current with a feed-forward anticipation action on the input network current. In this work we take advantage of a harmonic description of the electric car charger in order to propose a non-linear output feedback control based on sliding mode approach and Kalman filtering. The performance of the proposed control strategy is demonstrated via simulations realised in Matlab SimPowerSystems.
