Power Factor Enhancer (PFE) may be used in a power factor correction (PFC) controller to increase the power factor (PF) of a power converter. The PFE may provide controlled distortion of the sensed current of the power converter to improve PF. At high line input voltages, where power factor correction may be more difficult to achieve by other methods, the PFE may be enabled from light-load to full-load conditions. The PFE provides controlled distortion of the sensed current of the power converter to improve PF.
