A High Power Factor Flyback with Constant-Current Output for LED Lighting Applications
This article explains the principles of AC/DC converters in flyback topology having a high power factor input and a constant current output. The most commonly used mode of operation for this purpose is boundary conduction mode (BCM). The basics of this mode are developed and its drawbacks are made clear. A simple method for improving power factor is introduced and explained in detail. Operating in DCM mode improves power factor and THD while reducing the peak drain voltage. A quick design example is given and the special issues of driving high power LEDs are explained.
