An LED Driver with Adjustable Output Current

Abstract

In many occasions, it is necessary to remotely adjust the brightness of the LED and monitor the working state of the LED driving power. Aiming at this goal, this paper designs an LED driver with adjustable output current. The main structure of the circuit adopts APFC+LLC. The driving power is internally equipped with a power measurement module and a relay switch module, and the external power supply is equipped with wireless control module. It can realize adjust the LED light, and can also monitor the power consumption, input voltage, input current, power factor, output voltage and output current of the driving power supply.
