Abstract:
The present disclosure provides a line voltage compensation circuit, an LED drive system and a drive method. The line voltage compensation circuit is configured to receive signal reflecting bus voltage and output line voltage compensation signal based on the received signal reflecting bus voltage, a preset baseline voltage and at least one reference voltage, wherein the line voltage compensation signal has a multi-segment linear relationship with the received signal reflecting bus voltage. In the technical solution provided by the present application, the linear relationship between the feedback voltage of the LED load and the built-in baseline voltage is adjusted based on at least one preset threshold to output segment-based line voltage compensation signal. Compared with the line voltage compensation technology with a single slope, better input voltage line regulation and better LED current line regulation can be obtained by adopting the technical solution provided by the present application.
