Title:
LED CONSTANT-VOLTAGE CURRENT-SHARING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/177389
Kind Code:
A1
Abstract:
The present solution relates to the field of LEDs, and provides an LED constant-voltage current-sharing system. In the present solution, the system comprises a plurality of current-sharing modules, a plurality of direct-current power supplies, and an LED load module. The plurality of current-sharing modules is connected to the plurality of direct-current power supplies in one-to-one correspondence. Each current-sharing module detects an output voltage of corresponding direct-current power supply, and generates a balance voltage according to the output voltage. The plurality of balance voltages generated by the plurality of current-sharing modules is output to a current-sharing bus to generate a current-sharing bus voltage. Each current-sharing module generates a feedback signal according to the current-sharing bus voltage to adjust an output voltage of the corresponding direct-current power supply. Therefore, the current-sharing effect of a parallel power supply of the LED load module can be improved.
