Abstract :
In this paper, the small-signal model of a boundary conduction mode (BCM) boost power factor correction (PFC) converter controlled by a peak control current control IC L6561 is derived. Based on the derived mathematical model, a Type II compensator is thus well designed to make the boost converter exhibits the performances of high power factor and output voltage regulation. Finally, a 300 W prototype of the BCM boost PFC converter with IC L6561 is implemented. The performance of high power factor and power efficiency is validated by experimental results. Furthermore, the regulation of output voltage despite the variations of the peak line voltage and load resistances is also verified.
