Document Type and Number:
Japanese Patent JP6210324
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To switch a power supply circuit (converter or the like) which supplies power in the case of changing an operation mode between a power saving mode and a normal mode without largely changing a circuit scale at a load side.SOLUTION: A converter 16 is configured to operate in both a normal mode and a power saving mode, and a converter 14 is configured to operate in the normal mode, and to stop in the power saving mode. Then, diodes 18 and 20 are arranged on output lines 17 and 19 of the converters 14 and 16, and the output line 17 of the converter 14 and the output line 18 of the converter 16 are connected to a single power supply line 21, and power is supplied via the single power supply line 21 to a load.
