To provide a power distribution system capable of preventing a battery exhaustion by reducing a dark current while keeping component costs low.SOLUTION: A power distribution system includes: first paths B11, B12; a second path B2; first semiconductor switching elements Q5a1, Q5a2, Q5b1, and Q5b2 provided on of the first paths B11 and B12; a plurality of diodes D(1) to D(n) which are provided on the second path B2 and are serially connected; and a driver circuit 44 which can drive each of the first semiconductor switching elements Q5a1, Q5a2, Q5b1, and Q5b2 into an ON state with electric power supplied from a DC power supply 7. In the driver circuit 44, when the supply of electric power to a first load 5 from a power conversion device 1 is stopped, the electric power being supplied from the DC power supply 7 is stopped and the first semiconductor switching elements Q5a1, Q5a2, Q5b1, and Q5b2 are controlled into an OFF state.SELECTED DRAWING: Figure 1
【課題】部品コストを抑制しつつ、暗電流を低減させてバッテリ上がりを防止することができる電力分配システムを提供する。【解決手段】電力分配システムは、第１経路Ｂ１１，Ｂ１２と、第２経路Ｂ２と、第１経路Ｂ１１，Ｂ１２に設けられた第１半導体スイッチング素子Ｑ５ａ１，Ｑ５ａ２，Ｑ５ｂ１及びＱ５ｂ２と、第２経路Ｂ２に複数設けられ、直列に接続されたダイオードＤ（１）〜Ｄ（ｎ）と、直流電源７から供給される電力により第１半導体スイッチング素子Ｑ５ａ１，Ｑ５ａ２，Ｑ５ｂ１及びＱ５ｂ２をオン状態に駆動可能なドライバ回路４４と、を含む。ドライバ回路４４は、電力変換装置１から第１負荷５への電力の供給が停止した場合、直流電源７から供給される電力が停止され、且つ第１半導体スイッチング素子Ｑ５ａ１，Ｑ５ａ２，Ｑ５ｂ１及びＱ５ｂ２をオフ状態に制御する。【選択図】図１
