Resumo
This paper presents the design of a single-phase bidirectional plug-in electric vehicle (PEV) charger for charging/discharging the vehicle's battery. The charger operates in all quadrants of the active-reactive (P-Q) power plane, thus enabling reactive power support service to the utility grid. The proposed charger topology consists of two cascaded power stages: a full-bridge inverter and a coupled-inductor bidirectional Cuk converter. A hybrid control system is used, which consists of a set of PI controllers and Takagi-Sugeno (T-S) fuzzy controllers. This control system allows the charger to follow reference measures for active and reactive power in a smart grid environment. T-S fuzzy models are derived from the converter-inverter system for the controller's design analysis via linear matrix inequalities (LMI). Finally, the effectiveness of the proposed control strategy for the charger through simulation results is verified.
