To realize a configuration that can immediately supply power from another power supply source to a power supply target, more easily even when power supply from a power supply unit is interrupted.SOLUTION: In a backup circuit 1, a control unit 30 causes a second voltage conversion unit 12 to perform a voltage conversion operation in response to the establishment of a predetermined first backup condition, and when the control unit 30 causes the second voltage conversion unit 12 to perform the voltage conversion operation, a power supply unit side conductive path 71 and a power storage unit side conductive path 72 are conducted through a resistance unit 32. Further, the control unit 30 causes the first voltage conversion unit 11 to perform a second operation in response to the establishment of a predetermined second backup condition when the control unit causes the second voltage conversion unit 12 to perform the voltage conversion operation.SELECTED DRAWING: Figure 1

    【課題】電源部からの電力供給が途絶えた場合であっても、他の電力供給源からの電力を電力供給対象に対して即座に供給することができる構成を、より簡易に実現する。【解決手段】バックアップ回路1において、制御部30は所定の第1バックアップ条件の成立に応じて第2電圧変換部12に電圧変換動作を行わせ、制御部30が第2電圧変換部12に電圧変換動作を行わせているときには、電源部側導電路71と蓄電部側導電路72とが抵抗部32を介して導通する。更に、制御部30は、第2電圧変換部12に電圧変換動作を行わせているときに所定の第2バックアップ条件が成立したことに応じて第1電圧変換部11に第2動作を行わせる。【選択図】図1
