The invention discloses an integrated electric vehicle power conversion system. The system is characterized in that the system is provided with a set of multi-phase full bridge for driving a motor tooperate; the output point of at least one phase of the multi-phase full bridge is connected with a motor phase line and is also connected with the output point of the alternating current charging input filter; an additional bridge arm and a plurality of bridge arms in the multi-phase full bridge operated by the driving motor jointly form an alternating current charging input full bridge used for energy conversion during charging, and the additional bridge arm and the multi-phase full bridge operated by the driving motor are connected to the same direct current bus.
