In an automotive vehicle inverter control apparatus of the related art, a limp-home mode is provided, but six power sources including transformers are required for respective gate circuits of the respective IGBT drive circuits. Therefore, a reduction in size and a reduction in weight cannot be achieved, and a demand of the improvement of mountability or the improvement of fuel consumption as described above cannot be satisfied. A power semiconductor module and the drive circuit include three unit semiconductor modules and three unit drive circuits corresponding to a three-phase alternating current, and power supply units of the unit drive circuits are provided independently, whereby the limp-home mode is provided and in addition, the number of power supply units may be reduced, so that the reduction in size and the reduction in weight are achieved.
