Abstract:
A driver comprises a front-end stage, a back-end stage, and an intermediate controller. The front-end stage comprises a front-end main circuit and a front-end controller, and is configured to rectify an AC input voltage from an external power supply and output a DC bus voltage through output terminals. The back-end stage comprises a buck circuit, and configured to receive the bus voltage from the front-end stage and output a desired DC drive voltage to a load according to an operating voltage of the load. The intermediate controller is configured to obtain a difference voltage signal indicative of an electric potential difference between the bus voltage and the drive voltage, and provide a feedback signal generated based on the difference voltage signal to the front-end controller. The front-end controller controls the front-end main circuit based on the feedback signal to change the bus voltage with change of the drive voltage.

Claim (Index 3):
The driver as claimed in  claim 2 , wherein the intermediate controller comprises a first module configured to generate the difference voltage signal, and the first module comprising:\n a differential sampling circuit, wherein a first electrode of the controllable switch is connected with one input terminal of the differential sampling circuit and a second electrode of the controllable switch is connected with the other input terminal of the differential sampling circuit and the differential sampling circuit outputs a scaled potential difference between the first electrode of the controllable switch and the second electrode of the controllable switch; and a filter circuit which filters an output of the differential sampling circuit and outputs the difference voltage signal.
