Six-phase electrically-driven integrated V2G system and control method thereof

The invention discloses a six-phase electrically-driven integrated V2G system and a control method thereof. The six-phase electrically-driven integrated V2G system comprises a power grid side wiring terminal, a contactor group, a six-phase motor, a first converter, a first capacitor, a second converter, a second capacitor and a power battery, one end of the contactor group is electrically connected with the power grid side wiring terminal, and the other end is electrically connected with the six-phase motor; the six-phase motor is electrically connected with the AC side of the first converter. The DC side of the first converter is connected in parallel with the first capacitor. The high-voltage side of the second converter is connected in parallel to the first capacitor, and the low-voltage side of the second converter is connected in parallel to the second capacitor; the second capacitor is connected in parallel with the power battery; wherein the on-off state of the contactor group controls the operation mo
