Title:
SWITCHING POWER SUPPLY
Document Type and Number:
WIPO Patent Application WO/2015/178131
Kind Code:
A1
Abstract:
A DC/DC converter (2) working as a switching power supply comprises: a switching type power supply circuit (21) capable of executing a voltage conversion operation for converting an input voltage and generating an output voltage; and a control unit (22) for controlling the voltage conversion operation of the power supply circuit (21). The control unit (22) allows the power supply circuit (21) to execute the voltage conversion operation while the load factor of the power supply circuit (21) is a predetermined value or more. This brings about effects of enabling the power conversion efficiency to be improved and enabling the device to be prevented from increasing in size.
