Title:
POWER SUPPLY AND CONTROL METHOD THEREFOR
Document Type and Number:
Japanese Patent JP2023051555
Kind Code:
A
Abstract:
To provide a power supply which reduces the characteristic deterioration of an electric double-layer capacitor.SOLUTION: The power supply, which includes a first node connected to a power source and a grounded second node, includes a power storage circuit having an electric double-layer capacitor between the first node and the second node; a discharge circuit which includes a discharge resistor connected between the first node and the grounding; and a power control unit which measures the voltage of the first node to control the discharge circuit. The power control unit, on detecting a shift to a suspension state, starts discharging the power storage circuit by the discharge circuit. When the voltage of the first node becomes lower than a first reference voltage, the power supply executes the procedure of halting the discharge of the discharge circuit.SELECTED DRAWING: Figure 1
