The invention provides an integrated type electrical vehicle electrical energy conversion system. The system is characterized in that the input end of a motor module is connected with the output end of a three-phase alternating current module; a three-phase internal lock switch is connected between the output end of the three-phase alternating current module and the input end of the motor module in series; two phases of circuits are selected at random from three phases of circuits between the three-phase internal lock switch and the output end of the three-phase alternating current module to lead to a single-phase alternating current charging interface; the input end of the three-phase alternating current module is provided with a direct current charging interface; the three-phase alternating current module comprises three phases of bridge arms, and each phase of bridge arm is composed of an upper bridge arm and a lower bridge arm; the different working modes of the integrated type electrical vehicle electrical energy conversion system are achieved through controlling the on and off of the three-phase internal lock switch, the single-phase alternating current charging interface and the direct current charging interface; the control module comprises a power control unit of the three-phase alternating current module, and the power control unit generates a sine or direct current modulating wave; the sine or direct current modulating wave controls and superposes corresponding regulating variable under the different modes, and switch driving signals are generated through the PWM modulating.
