Abstract
An inverter device is provided with a semiconductor device, an input terminal, an intermediate terminal, an output terminal and an insulated substrate on which the semiconductor device, the input terminal, the intermediate terminal and the output terminal are mounted. Each of the input terminal, the intermediate terminal and the output terminal is a separated module such that one of the input terminal, the intermediate terminal and the output terminal is spatially independent from the other.
Claims5
An inverter device, comprising:
- a semiconductor device;
- an input terminal;
- an intermediate terminal;
- an output terminal;
- and
- an insulated substrate on which the semiconductor device, the input terminal, the intermediate terminal and the output terminal are mounted,
- wherein the input terminal has a resin main body, a bus bar projected from the resin main body and a pad portion connected to the insulated substrate, the intermediate terminal has a resin main body, a connecting pin projected from the resin main body and a pad portion connected to the insulated substrate, and the output terminal has a resin main body, a bus bar projected from the resin main body and a pad portion connected to the insulated substrate,
- wherein the pad portion of each of the input terminal, the intermediate terminal and the output terminal is adhered onto a surface of a metal layer as a pad surface of the insulated substrate by forming a solder connecting portion therebetween, while being aligned to the surface of the metal layer as the pad surface,
- and wherein the resin main body of each of the input terminal, the intermediate terminal and the output terminal is separated one another on the insulated substrate, with each of the input terminal, the intermediate terminal and the output terminal being for the semiconductor device to be an separated module such that one of the input terminal, the intermediate terminal and the output terminal is spatially independent from the other.
