Title:
VOLTAGE SUPPLY SYSTEM AND POWER SOURCE CONSTITUTING SAME
Document Type and Number:
WIPO Patent Application WO/2020/084822
Kind Code:
A1
Abstract:
Provided are: a voltage supply system in which a plurality of power sources (for example, DC-DC converters) are connected in parallel, wherein it is possible to set each power source to an arbitrary load ratio; and a power source. The power source: is used in the voltage supply system which includes power sources that output a voltage in a constant voltage mode on the basis of a first target voltage; and is connected in parallel to a constant voltage power source. The power source includes a voltage generation unit that outputs a voltage by switching between a constant voltage mode based on a second target voltage that is higher than the first target voltage and a constant current mode based on a current limit value.
