Abstract: Provided is a backup power supply that efficiently supplies power under the control of a microcomputer. The backup power supply is charged by a rectifier for generating power of a predetermined voltage, and supplies power to a load device operating with power supplied from the rectifier when the supplied power is insufficient. The backup power supply includes a secondary battery to be charged with power from the rectifier, a control unit for controlling charging and discharging of the secondary battery, and an input/output voltage detection unit for detecting the output voltage from the rectifier. The control unit stops charging of the secondary battery or reduces a charging current flow of the secondary battery when the output voltage drops to a first threshold voltage or less.

Abstract: When DC power to be supplied from a main power supply device drops and a voltage to be input to a load falls below a predetermined threshold value, a microcomputer controls a switch unit so as to start an ON-operation for supplying the DC power from a sub power supply device to the load, and when the DC power to be supplied from the main power supply device recovers, the microcomputer controls the switch unit so as to start an OFF-operation for restricting the DC power to be supplied from the sub power supply device to the load, restrict supply of the DC power from the sub power supply device to the load so that a voltage to be input to the load does not fall below a predetermined threshold value until a predetermined time has elapsed since start of the OFF-operation, and set supply of the DC power from the sub power supply device to the load to zero after the predetermined time has elapsed.
