Thesis Work:
An Efficient and Cost-Effective Low-Power LED Driver with Power Factor Correction, Soft-Switched Converters and Controllable PWM Units
An efficient design of an electrically isolated low-power LED driver with active power factor controller (PFC) based on buck converter topology comprising a rectifier-fed-PFC unit which reduces the harmonic distortion of the mains line current by improving the sending-end power factor. There is a dc-link-inverter which consists of a soft switched buck converter and a parallel-loaded series L-C resonant inverter. At the receiving-end, there is a high frequency transformer provided isolation and a rectifier to feed appropriate voltage and current to a 12 W LED lighting load.
