Abstract: A motor control apparatus 1 includes an inverter 10, a smoothing capacitor 11, power-converting drivers 120 to 125, a power-converting power supply circuit 13, and discharging drivers 140 and 141. The inverter 10 includes switching circuits 100 to 102 comprised of series-connected two IGBTs. The power-converting drivers 120 to 125 apply an output voltage of the power-converting power supply circuit 13 to the switching circuits 120 to 125 to drive them, thus performing power conversion. The discharging drivers 140 and 141 simultaneously turn on IGBTs 100a and 100b of the switching circuit 100 to discharge the smoothing capacitor 11 when the output voltage of the power-converting power supply circuit 13 is equal to or lower than a threshold. This prevents discharging of the smoothing capacitor during power converting operations.

Abstract: A drive circuit supplies a charging current via a charging path to drive the control terminal of a voltage-controlled switching device, with a resistor and a switching device being connected in series in the charging path. A control circuit in an integrated circuit of the drive circuit operates an internal switching device such as to selectively enable/interrupt the charging current and to regulate the voltage drop across the resistor to a fixed value. The switching device connected in the charging path can be readily changed from the internal switching device to an external switching device, in accordance with the operating requirements of the driven switching device.
