To provide a power system which allows load sharing in a state without voltage deviation of a DC line.SOLUTION: A power system comprises: a plurality of DC/DC converters 10 connected in parallel with a DC bus line; and a plurality of DC/DC converter controllers 22 which performs proportional plus integral control for each of the DC/DC converters, and in which an integrated value of difference between voltage V_bus of an actual DC bus line and a voltage target value V_ref of the DC bus line is shared so as to arbitrarily control load sharing of the plurality of DC/DC converters 10.SELECTED DRAWING: Figure 3 【課題】直流ラインの電圧偏差がない状態において負荷分担が可能な電力システムを提供する。【解決手段】ＤＣバスラインに並列接続された複数のＤＣ／ＤＣコンバータ１０と、ＤＣ／ＤＣコンバータの各々を比例積分制御する複数のＤＣ／ＤＣコンバータ制御器２２と、を備え、複数のＤＣ／ＤＣコンバータ制御器２２において、実際のＤＣバスラインの電圧Ｖ＿ｂｕｓとＤＣバスラインの電圧目標値Ｖ＿ｒｅｆとの差分の積分値を共有することで、複数のＤＣ／ＤＣコンバータ１０の負荷分担を任意に制御する。【選択図】図３
