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 5):
The driver as claimed in  claim 3 , wherein\n the difference voltage signal is directly provided to the front-end controller as the feedback signal; and the front-end controller is configured to control the difference voltage signal to follow a predefined difference voltage reference based on the difference voltage signal and the predefined difference voltage reference, so as to maintain the electric potential difference between the bus voltage and the drive voltage within a predetermined range.
