Title: POWER SUPPLY DEVICE AND METHOD FOR CONTROLLING POWER SUPPLY DEVICE
Abstract:
An auxiliary power supply device 20 is provided with a capacitor 22, a charging circuit 24 for charging the capacitor 22, a control circuit 21 which is connected so as to be capable of receiving a power supply from a battery 11 and the capacitor 22 and which is capable of controlling the charging circuit 24, and a power feed switch 27 which is disposed in the path between the battery 11 and the control circuit 21 and which is capable of switching between an on state in which power is supplied from the battery 11 to the control circuit 21 and an off state in which power is not supplied from the battery 11 to the control circuit 21, the control circuit 21 performing a control so that the power feed switch 27 is in the off state when an ignition switch 13 is off.
