電源維持装置
Document Type and Number:
Japanese Patent JP7046623
Kind Code:
B2
Abstract:
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
