In order to eliminate the ripple of the active power and suppress the negative sequence current produced during the charging process of the tramcar under both balanced and unbalanced power supply conditions, a novel proportional integral resonance based sliding mode (PIRSM) control scheme is proposed in this article for the VIENNA rectifier of the charging station. After deriving the power model in the stationary coordinate system, the mathematical model of the VIENNA rectifier under unbalanced power supply is built. Subsequently, a unified control objective is introduced to make the proposed scheme available for different operating condition without changing the algorithm. Moreover, the resonance control and sliding mode control are combined together to construct the sliding mode surface, and the control law are derived based on the stability requirement to make the system approach its desired operating point with expected trajectory. Experimental results show that compared to the conventional PI control, the proposed control can ensure the better power tracking performances and higher power quality under different power supply conditions.
