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.

Claim (Index 10):
An electrically driven vehicle inverter device provided to a drive circuit for a motor that generates a drive force for a vehicle, comprising:\n a smoothing capacitor; a discharge resistor, one end of which is electrically connected to a positive electrode side of the smoothing capacitor; a first discharge switching element including a gate and electrically connected to an other end of the discharge resistor in such a manner as to be electrically connected in series with the discharge resistor; a second discharge switching element including a gate and electrically connected between the discharge resistor and the first discharge switching element and a ground; a control circuit that directly applies, to the gate of one of the first discharge switching element and the second discharge switching element, a signal for turning on the gate; time difference setting circuit configured to set a time difference with which the other of the first discharge switching element and the second discharge switching element starts being turned on after the one switching element is turned on; and a clamp circuit that is provided for the other switching element and that restricts a voltage across the other switching element so as not to exceed an upper-limit value determined in advance.
