POWER SUPPLY DEVICE

To provide a power supply device which can easily change a load whose power supply is made redundant.SOLUTION: A power converter 130 is connected between a first power supply terminal 110 for connecting a first power supply, and a second power supply terminal 120 for connecting a second power supply. A cut-off circuit 140 is connected between the first power supply terminal 110 and the power converter 130. A first switch 150 and a second switch 160 are connected between a first connection point CP1 between the power converter 130 and the cut-off circuit 140 and a second connection point CP2 between the power converter 130 and the second power supply terminal 120. A plurality of load terminals 170 for connecting to the load and a plurality of load switches 180 corresponding to the plurality of load terminals 170 by one to one are provided. Each of the plurality of load terminals 170 is connected to a line connecting the first switch 150 and the second switch 160 via the corresponding load switch 180.SELECTED DRAWING: Figure 1 【課題】電源冗長化する負荷の変更が容易な電源装置を提供する。【解決手段】第１の電源を接続するための第１の電源用端子１１０と、第２の電源を接続するための第２の電源用端子１２０と、の間に電力変換器１３０を接続し、第１の電源用端子１１０と電力変換器１３０との間に遮断回路１４０を接続し、電力変換器１３０と遮断回路１４０との間の第１の接続点ＣＰ１と、電力変換器１３０と第２の電源用端子１２－との間の第２の接続点ＣＰ２と、の間に第１のスイッチ１５０および第２のスイッチ１６０を接続し、負荷と接続するための複数の負荷用端子１７０と、複数の負荷用端子１７０と一対一に対応している複数の負荷用スイッチ１８０と、を備えるようにし、複数の負荷用端子１７０の各々を、対応する負荷用スイッチ１８０を介して、第１のスイッチ１５０と第２のスイッチ１６０とを接続するラインに接続する。【選択図】図１
