Abstract

The radiated noise of a semiconductor device is conveniently evaluated, and the radiated noise of an apparatus equipped with the semiconductor device is estimated. An evaluation method including: making a semiconductor device that is connected parallel to a load by a load cable, perform a switching operation; measuring common-mode current flowing through the load cable during the switching operation; and outputting an evaluation benchmark for radiated noise based on the common-mode current, and an evaluation apparatus are provided.
