Abstract
An electrically driven vehicle inverter device includes a smoothing capacitor, a discharge resistor, a discharge resistor and first and second discharge switching elements connected in series between both ends of the smoothing capacitor, and a clamp circuit provided for at least one of the first and second discharge switching elements. The clamp circuit includes a reverse flow prevention element and a constant voltage generation element that causes a constant voltage drop when a voltage across the constant voltage generation element exceeds a value determined in advance, for example.
