Abstract

The power converter for solving the above-described problem has a module section and a drive section for operating the module section. The drive section has a drive circuit. The drive circuit is provided so as to correspond to the first semiconductor element which is one of the semiconductor elements comprising the parallel circuit; wherein drive signals for operating the first semiconductor element are output. The drive signals that are output from the drive circuit are electrically branched and output to a second semiconductor element which is a separate semiconductor element from the first semiconductor element of the semiconductor elements comprising the parallel circuit. As a result, the second semiconductor element receives the branched drive signals and operates in the same manner as the first semiconductor element. Thereby, a motor converter favorable for control large current at a low cost is provided.
