Title:
スイッチング電源装置及び空気調和機
Document Type and Number:
Japanese Patent JP5822720
Kind Code:
B2
Abstract:
For a load circuit (10c) having a load (14) requiring electric power supply at the time of a stand-by operation mode, an output voltage is set to 5 V that is the lowest voltage of the voltage of a supply load which is required at the time of the stand-by operation mode. Further, in the load circuit (10c), for a load (15) requiring a load voltage higher than the output voltage of 5 V at the time of a normal operation mode, an output voltage is boosted by boosting means such as a boost converter (21) and then supplied. Thus, power consumption at the time of the stand-by operation mode can be reduced.
