| description | To provide an electrical power system and an electrical power device which can raise an alarm when a butted FET turns to be off.SOLUTION: In an electrical power system with at least two electrical power devices 10 which supply current to a load, the electrical power device 10 comprises: a converter 11 which generates current being supplied to the load; an FET 13 which is connected in series between the converter and the load; a gate voltage monitoring circuit 16 which monitors whether or not a gate voltage of the FET 13 falls below a prescribed first reference voltage; and an alarm generation circuit 17 which generates an alarm according to results of monitoring by the gate voltage monitoring circuit.SELECTED DRAWING: Figure 2
【課題】突き合わせＦＥＴがオフ状態になった場合に、アラームを発報することができる電源システム及び電源装置を提供する。【解決手段】負荷に対して電流を供給する少なくとも２台の電源装置１０を備える電源システムにおいて、電源装置１０は、負荷に供給する電流を生成するコンバータ１１と、コンバータと負荷との間に直列に接続されているＦＥＴ１３と、ＦＥＴ１３のゲート電圧が予め規定された第１基準電圧を下回ったか否かを監視するゲート電圧監視回路１６と、ゲート電圧監視回路の監視結果に応じてアラームを生成するアラーム生成回路１７と、を備える。【選択図】図２ |
