To provide a power supply maintenance device capable of solving problems for example, in cranking or the like of a vehicle, a voltage of power supplied by a power supply circuit 21 is reduced and a control circuit cannot operate normally.SOLUTION: A voltage maintenance device 1 is configured so that, by connecting first wiring WR1 and second wiring WR2 by a switch circuit 7, power accumulated in an inverter capacitor 10 is started to be supplied to a power supply circuit 21. Therefore, the power supply circuit 21 can generate power without reducing a voltage of the power, and the control circuit can normally operate continuously.SELECTED DRAWING: Figure 1

    【課題】車両のクランキング等のときに、電源回路21が供給する電力の電圧が低下し、制御回路が正常に動作することができなくなるおそれがあった。【解決手段】電圧維持装置1は、スイッチ回路7が、第1の配線WR1と第2の配線WR2とを接続することにより、インバータコンデンサ10に蓄積された電力が、電源回路21に供給され始める。これにより、電源回路21は、電力の電圧を降下させることなく生成することができ、制御回路は、正常に動作し続けることが可能となる。【選択図】図1
