In order to realize the bidirectional flow of energy between electric vehicles and the power grid in Vehicle to Grid (V2G) mode, this paper analyzed the working principle using the non-isolated two-stage bidirectional AC/DC converter as the research object, a mathematical model was established. The feed forward decoupling double closed-loop, constant current charge and discharge control strategies were formulated. The Space Vector Pulse Width Modulation (SVPWM) technology was utilized to generate the driving signal of the power switch tube, the passive damping LCL filter was designed. Finally, the system simulation model was built in MATLAB/Simulink for system simulation and analysis. The results show that the proposed control strategy can realize the bidirectional power flow between the electric vehicle and the power grid.
