Title:
DC POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/024775
Kind Code:
A1
Abstract:
Output sides of a plurality of DC power supply devices (10A-10E), which are CVCC power supplies, are connected in parallel to a load (120). In each of the plurality of DC power supply devices (10A-10E), an upper limit current (Icc), which is maintained in a CC mode, is designed to be equal to or smaller than a rated current. The output voltages of the plurality of DC power supply devices (10A-10E) are actually different due to unevenness within an allowable voltage range of the load 120 with respect to an equally set reference voltage Vr. The plurality of DC power supply devices (10A-10E) operates, in response to an increase in an output current (Iout) to the load (120), so as to supply a current accompanied by a transition from a CV mode to the CC mode in an order from a DC power supply device of which an actual output voltage is high.
