PROBLEM TO BE SOLVED: To provide a power supply device capable of suppressing loss and detecting current.SOLUTION: A power supply device includes a plurality of voltage conversion units connected in parallel between an input terminal and an output terminal. The power supply device includes a plurality of current path units each of which connects the output terminal and each of the plurality of voltage conversion units, and a current detector interposed in at least one of the plurality of current path units. For example, the number of voltage conversion units and the number of current path units are represented by N and the current detected by the current detection units is represented by I. In this case, when the respective voltage conversion units output the same current, the output current of the power supply can be calculated as N×I.SELECTED DRAWING: Figure 2

    【課題】損失を抑制して電流を検出することができる電源装置を提供する。【解決手段】電源装置は、入力端と出力端との間に並列に接続された複数の電圧変換部を備える。電源装置は、出力端と複数の電圧変換部それぞれとを接続する複数の電流経路部と、複数の電流経路部の少なくとも1つに介装された電流検出部とを備える。例えば、電圧変換部の数及び電流経路部の数をNとし、電流検出部で検出した電流をIとすると、各電圧変換部が出力する電流が同等であるとすると、電源装置の出力電流は、N×Iで求めることができる。【選択図】図2
