PROBLEM TO BE SOLVED: To provide a power control unit capable of minimizing total evaluation of cost, loss, and volume and weight.SOLUTION: A power controller is installed in a vehicle and includes a plurality of switching arms in which a transistor is connected with a diode inversely in parallel. While part of the switching arms is formed by a complex type semiconductor chip in which a diode is built-in in a transistor, other switching arms are formed by a first single-handed type semiconductor chip having at least one single-handed transistor and a second single-handed type semiconductor chip having a single-handed diode.SELECTED DRAWING: Figure 2 【課題】コスト、損失及び容積・重量の総合評価を最小化し得るパワーコントロールユニットを提供する。【解決手段】車両に搭載され、トランジスタにダイオードが逆並列接続された複数のスイッチングアームを備えるパワーコントロールユニットであって、一部のスイッチングアームは、トランジスタにダイオードが内蔵された複合型半導体チップにより形成され、他のスイッチングアームは、少なくとも１つの単独のトランジスタを備えた第１の単独型半導体チップと単独のダイオードを備えた第２の単独型半導体チップにより形成されている。【選択図】図２
