Abstract :
A new control strategy and circuit topology structure of electric vehicle charging and discharging inverter based on space vector is presented. The control strategy uses rotation vector of the directional three-phase active tide reversible PWM converter, and the circuit topology is two-way control DC/DC converter with double buck reversible structure. In order to improve the efficiency of the charging and discharging machine, the main circuit of the machine adopts isolation method, which is suitable for high power direct voltage battery group. Simulation and experimental results show that the double buck reversible structure has the function of electric power flowing with two-way, the transmission power factor is 1, and the harmonic is under control within 2%, the effectiveness of the proposed method is confirmed.
