Abstract

The goal of this final year project is to produce an LED Driver using IoT technology for a smart street lighting system. The AC-DC Rectifier, Power Factor Correction (PFC), and DC-DC Buck Converter are included in this LED Driver. This entire device will convert AC into desired DC level which is ideal for the LED streetlight to light up. The rectifier will be designed to transform AC into DC supply. This system consists of Power Factor Correction (PFC) to obtain a better power factor and improved harmonic distortion. Based on the parameters of the LED Driver module in Appendix A, the desired DC output voltage range is 65-100V. The open-loop and closed-loop buck converter will be simulated by using MATLAB Simulink. The PI controller is designed and implemented into the closed-loop buck converter. Arduino is used as a PI controller to control the duty cycle and inject signal to the MOSFET. The main purpose is to achieve a constant output voltage based on the reference voltage. Simulation and hardware work are both going to be completed. MATLAB Simulink will be used to design and develop the LED Driver.
