To prevent a cost increase and system complication due to an addition of communication lines for controlling power supply device and checking a status.SOLUTION: A power supply device 100 includes a plurality of battery modules 102. The battery modules 102 are connected in series with each other according to a gate drive signal from a controller 104. After delaying the gate drive signal in a gate drive signal processing circuit 20 included in each of the battery modules 102, the gate drive signal is transmitted from upstream to downstream of a series connection. The battery module 102 is controlled by superimposing the control signal for the battery module 102 on the gate drive signal.SELECTED DRAWING: Figure 1 【課題】電源装置の制御や状態確認を行うために通信線を追加することによるコスト上昇やシステムの複雑化を防止する。【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、ゲート駆動信号を電池モジュール１０２の各々に含まれるゲート駆動信号処理回路２０において遅延させた後に直列接続の上流から下流に向けて伝達させる電源装置１００であって、電池モジュール１０２に対する制御信号をゲート駆動信号に重畳させることによって電池モジュール１０２を制御する。【選択図】図１
