To provide a power source integration system with a motor driving function and a battery charging and discharging function.SOLUTION: A power source integration system includes a motor, a power source integration circuit, and a battery connected to the power source integration circuit. The motor includes a multiphase circuit in which each phase includes an inductor. The power source integration circuit includes: an inverter having a multiphase bridge arm, in which the bridge arm of each phase includes an upper switch and a lower switch and the bridge arm of each phase is connected to each inductor of the multiphase circuit of the motor; and a charger including a switch disposed in connection between the bridge arms of any two phases among the multiphase bridge arm, the upper switch and the lower switch of the bridge arm of at least one phase among the multiphase bridge arm to be shared with the inverter, and an inductor to be shared with the motor. The power source integration circuit receives DC power source supplied from a DC power source device. The charger charges the battery by converting the DC power source and the battery supplies power necessary to drive the motor through the inverter.SELECTED DRAWING: Figure 1
