Abstract
The present invention relates to a semiconductor device used in power equipment. The semiconductor device includes: a base plate; an insulating substrate mounted on the base plate; a power switching element bonded to the insulating substrate with a solder layer; and the base plate, the insulating substrate, and the power switching element forming a module, a control substrate located above the module. The control substrate includes a variable gate voltage circuit measuring a collector-emitter voltage of the power switching element and changing a gate voltage such that the power switching element is supplied with given target power determined by a product of the collector-emitter voltage and a collector current.
