    Abstract: Each of a first and a second inverter circuit supplies a driving current to an electric motor in a different power supply line. A custom IC has a first pre-driver circuit for outputting control signals to the first inverter circuit and a second pre-driver circuit for outputting control signals to the second inverter circuit. A micro-computer for outputting operation signals to the first and second pre-driver circuits is mounted to a control board on a center line. A distance between the center line and the first inverter circuit and a distance between the center line and the second inverter circuit is equal to each other. First and second output terminals of the micro-computer as well as first and second input and output terminals of the custom IC are symmetric with respect to the center line.

    Abstract: A vehicle includes a converter for stepping up power provided from a power storage device, and an inverter for converting the power output from converter and outputting it to an alternating-current motor for driving the vehicle. In the vehicle, a rectangular voltage control unit controls the inverter by means of rectangular wave voltage control that is based on a torque command value and the like, so as to control an output torque of the alternating-current motor. A system voltage control unit controls a system voltage, which is an output voltage of the converter. The system voltage control unit lifts a restriction on a system voltage command value based on an accelerator pedal position and the like, and then increases it. When increasing the system voltage command value during the rectangular wave voltage control for the inverter, a cooperative control unit increases the system voltage command value and the torque command value in a cooperative manner.
