Abstract
An inverter circuit includes an IGBT () and an IGBT () connected in series between a power supply potential (Vcc) and a GND potential, and an HVIC () and an LVIC () for respectively controlling actuation of the IGBTs () and (). The inverter circuit also includes a capacitor (), a diode (), and a resistor (). The capacitor () is connected between a terminal (VS) and the GND potential. The diode () has a series connection to the capacitor () between the terminal (VS) and the GND potential, with such a polarity that a forward current flows from the GND potential to the terminal (VS). The resistor () is connected in parallel to the capacitor ().
