    • A semiconductor device in which a bipolar transistor and a MOS transistor are formed in a common element region, which can prevent a circuit layout pattern from being large due to a wiring. A semiconductor device having an element region formed by the N−-type layer, which is isolated and insulated from the other regions. A P+-type base region, an N−-type emitter region, an N+-type collector region, and a P+-type excess carrier removing region for removing excess carrier in the P+-type base region, are commonly formed in particular one N−-type layer. Thus, a bipolar transistor is defined. Furthermore, a gate oxide film is formed on the surface of the N−-type layer where between the P+-type base region and the P+-type excess carrier removing region. A polysilicon layer is formed on the gate oxide film. Thus, a P+-type MOS transistor is defined by using the P+-type base region as a source and the P+-type excess carrier removing region a drain. The P+-type base region, the P+-type excess carrier removing region, the N−-type emitter region, the N+-type collector region, and the polysilicon layer are respectively connected to metallic electrodes. Since the bipolar transistor and the MOS transistor are commonly formed in an element region, and one of regions is commonly used, it can prevent a circuit layout pattern from being large due to a wiring for connecting the bipolar transistor and the MOS transistor.

    • A drive unit controls the operation of a corresponding power switching element such as IGBT which forms an inverter and a converter. The drive unit controls the operation of the corresponding power switching element to supply an operation current to a motor generator. First and second switching elements in the drive unit are simultaneously turned on when an operation signal transferred from a control device is switched to a turning-on instruction operation signal. The voltage at the gate terminal of the power switching element is shifted to a divided voltage obtained by dividing a voltage of the power source by first and second resistances connected in series in the drive unit. When a mirror time period of the power switching element is elapsed, the second switching element only is turned off in order to shift the gate voltage of the power switching element to the voltage of the power source.
