POWER SUPPLY CONTROLLER
Document Type and Number:
Japanese Patent JP2018078743
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To make effective use of regenerative electric power with a relay in an off state.SOLUTION: A power supply controller 1, connected with a power supply B for vehicle, a step-up power supply P and a coil R1 of a relay R, includes: a regenerative switching transistor 5 arranged between the step-up power supply P and the power supply B for vehicle; a control unit 9 for switching between on and off states of the regenerative switching transistor 5 on the basis of a voltage of a capacitor P1 of the step-up power supply P and a voltage of a capacitor B2 of the power supply B for vehicle.SELECTED DRAWING: Figure 1
