Abstract
The power conversion apparatus uses the semiconductor device. Said semiconductor device includes a first group of power semiconductor elements at least one of which is electrically connected between a first potential and a third potential, a second group of power semiconductor elements at least one of which is electrically connected between a second potential and the third potential, and a third group of power semiconductor elements at least one of which is electrically connected between the first potential and the third potential. The second group is disposed between the first group and third group. Thereby, a low-loss semiconductor device having both inductance reducibility and heat generation balancing capability and also an electric power conversion apparatus using the same is provided.
