Abstract
An electric power converter includes a semiconductor module that has a semiconductor element therein, a cooler that cools the semiconductor module, a circuit board provided with a semiconductor control circuit that controls the semiconductor module, a capacitor electrically connected to the semiconductor module, and a quick discharge resistor for discharging an electric charge accumulated in the capacitor. The circuit board is provided with a discharge control circuit that controls a current that flows into the quick discharge resistor. The semiconductor module, the cooler, the capacitor, and the quick discharge resistor are disposed on one major surface of the circuit board.
