Abstract:
A power conversion apparatus is provided in which an upper arm semiconductor device, a lower arm semiconductor device and a capacitor. At least either upper arm semiconductor device or lower arm semiconductor device constitutes a parallel-connected body. In an opposite arm against the parallel-connected body, a permissible element is provided. In the switching elements that constitute the parallel-connected body, a last off element and a non-last off circuit are identified. Inductance of a last off closed circuit where current flows through the last off element, reflux element in the opposite arm and the capacitor is smaller than inductance of a non-last off closed circuit where current flows through the last off element, reflux element in the opposite arm and the capacitor.

Claim (Index 10):
The power conversion apparatus according to  claim 1 , wherein\n the parallel-connected body of the upper arm semiconductor device includes the last off element, the non-last off element and the reflux permissible diode, and the parallel-connected body of the lower arm semiconductor device includes the last off element, the non-last off element and the reflux permissible diode; the last off element, the non-last off element and the reflux element in the upper arm semiconductor device, and the last off element, the non-last off element and the reflux element in the lower arm semiconductor device are mounted to a leg common module as a single common semiconductor module; the leg common module is configured such that a high potential terminal connected to the upper arm semiconductor device, a low potential terminal connected to the lower arm semiconductor device and an output terminal connected to the upper arm semiconductor device and the lower arm semiconductor device are protruded from a module body; total inductance of a wiring path in the module body which connects the high potential terminal and the low potential terminal, passing through the last off element and the reflux element which belong to mutually opposite arm is smaller than total inductance of a wiring path in the module body which connects the high potential terminal and the low potential terminal passing through the non-last off element and the reflux element which belong to a mutually opposite arm.
