Title:
CIRCUIT FOR IMPROVING POWER SUPPLY STARTING TIME, AND DRIVING POWER SUPPLY
Document Type and Number:
WIPO Patent Application WO/2020/062818
Kind Code:
A1
Abstract:
The present invention relates to a circuit for improving a power supply starting time, and a driving power supply. The circuit comprises: a control IC, a starting adjustment circuit, a switch circuit, a power supply circuit and a charging capacitor, wherein the high-voltage signal input end of the control IC is connected to an output end of a rectified bus voltage, a power supply end of the control IC is connected to the starting adjustment circuit, the starting adjustment circuit is connected to the switch circuit and the charging capacitor respectively, and the switch circuit and the charging capacitor are further connected to the power supply circuit respectively. According to the present invention, the starting time of the power supply can be effectively shortened when the power supply is started by means of providing the starting adjustment circuit, avoiding the phenomenon that an LED lamps on the load are lit without coordination due to the fact that the starting time of the power supply is different or too long.
