To properly control the number of battery modules that are forcibly disconnected in a power supply device.SOLUTION: A power supply device 100 includes a plurality of battery modules 102. The battery modules 102 are connected in series to each other according to a gate drive signal from a controller 104. Disconnecting means for forcibly disconnecting the battery module 102 from the series connection regardless of the gate drive signal is included. The number of the battery modules 102 that are forcibly disconnected by the disconnecting means is limited according to an output target voltage value.SELECTED DRAWING: Figure 1 【課題】電源装置において強制的に切り離される電池モジュールの数を適切に制御する。【解決手段】電池モジュール１０２を複数含み、制御コントローラ１０４からのゲート駆動信号に応じて電池モジュール１０２が相互に直列接続される電源装置１００であって、ゲート駆動信号に関わらず電池モジュール１０２を直列接続から強制的に切り離す切断手段を備え、出力目標電圧値に応じて切断手段によって強制的に切り離される電池モジュール１０２の個数を制限する。【選択図】図１
