A traditional flyback LED driver is limited by its low performance, which usually does not meet the power factor (PF) and total harmonic distortion requirements according to Energy Star or IEC61000-3-2. The control loop from the secondary side to the primary side has low reliability and employs more components, which reduces the power density of the system and increases the cost. In this brief, based...
Traditional flyback LED driver is limited by its low performance which usually dissatisfy the power factor (PF) and Total Harmonic Distortion (THD) according to Energy Star or IEC61000-3-2. The control loop from secondary-side to the primary-side has low reliability to reduce the working lifetime and employs more components, which reduces the power density of system. In this paper, based on single-stage...
