Title:
Electrical equipment
Document Type and Number:
Japanese Patent JP6330772
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electric apparatus capable of preventing an excessive rush current which may be generated at restoration from a sleep mode.SOLUTION: A power supply unit 30 includes: a control voltage generator circuit (secondary side feedback circuit 32) which generates a control voltage according to an on/off state of a sleep signal and an output voltage; and a control circuit (power control IC 31, secondary side feedback circuit 32, primary side feedback circuit 33) which controls, based on the control voltage, an output voltage Vo to a normal voltage if the sleep signal is off, and controls the output voltage Vo to a sleep voltage, which is lower than the normal voltage, if the sleep signal is on. A body part 20 includes a control voltage adjustment circuit 23 which, when the sleep signal is switched from on to off, adjusts the control voltage generated by the control voltage generator circuit, so as to control the output voltage to be an intermediate voltage, which is higher than the sleep voltage and lower than the normal voltage, according to the inside temperature of the body part 20.SELECTED DRAWING: Figure 1
