Abstract

This thesis presents a robust control strategy of a three-phase off-board AC-DC battery charger for electric vehicle. Intelligent constant current-constant voltage (CC-CV) charger for fast charging a Lithium-ion battery. Increasing the charging current in the CC regime cannot guarantee the short charging time, so an optimal charging current exists in the CC-CV method. The proposed control consists of inner-loop robust control and outer-loop conventional PI control. For the inner-loop robust control, a state feedback controller with integral action is employed in dq-synchronous frame. The set of stabilizing gains of this controller are determine by a Linear Matrix Inequality (LMI)-based optimization so that the convergence time to steady state is minimized in the occurrence of the parametric uncertainties of the L-filter. The efficacy of the proposed controller is verified through simulation results on 650V and 10A of batteries equivalent circuit on PSIM.
