Abstract
There has been a problem that a chip or a power module is broken by a repulsive electromagnetic force between positive and negative bus bars and an arc is generated, so that the failure is escalated. Therefore, positive and negative bus bars connecting two devices are configured so as to form a one-turn-loop current path, thereby suppressing a repulsive electromagnetic force occurring between the bus bars and decreasing a possibility of occurrence of an arc at the power module.
