A Digital Power Factor Controller for Primary-Side-Regulated LED Driver

A Digital Power Factor Controller for Primary-Side-Regulated LED Driver

In this study, a digital primary-side controller for a flyback light-emitting diode driver with superior line regulation, high power factor (PF), and low total harmonic distortion (THD) was proposed. Conventional constant on-time control is hampered by input current distortion, leading to high THD....
