ABSTRACT:
In an inverter device, two short-circuiting bars of a direct current circuit portion are each formed of a conducting plate bent so as to have a crank-shaped cross section, one of the outside flat surfaces of each of the two conducting plates is connected to the input end of each semiconductor switching element, and the other outside flat surfaces of the respective conducting plates are superimposed on each other, in close proximity, via an insulating sheet. This construction reduces the difference in wiring inductance between the closest element to and the farthest element from a smoothing capacitor when the device is turned on, and also decreases the current imbalance between them.
