Title:
ELECTRIC POWER SUPPLY DEVICE, LIGHT DEVICE, AND METHOD FOR SUPPLYING ELECTRIC POWER
Document Type and Number:
WIPO Patent Application WO/2024/042699
Kind Code:
A1
Abstract:
In an electric power supply device, the supply voltage changes due to a change in the supplied electric current, and thus stable operation of the load becomes difficult. Therefore, an electric power supply device according to the present invention comprises: a constant voltage generation means that receives a supply of a first branch electric current that is included in a supply electric current, and generates a constant voltage; a first control means through which flows a second branch electric current that is included in the supply electric current; and a second control means through which flows a third branch electric current that is included in the supply electric current, wherein the second control means controls the third branch electric current such that the sum of the second branch electric current and the third branch electric current becomes constant.
