Abstract

See full text

The various embodiments may include a power supply having a first loop in communication with a power stage of the power supply. A second loop in communication with the first loop may generate a negative reactance value that increases a power factor for the power supply to approximately one. A power supply may also include a rectifier coupleable to an input supply. A power factor compensation circuit coupled to the rectifier may generate a negative reactance. The negative reactance may reduce a phase angle between a current and a voltage provided to the input supply. A method may include sensing an output of a power supply, and adjusting the sensed value. The adjusted value may be compared to a reference value to generate an error value. The error value and a negative reactance value may be combined and the result may be provided to the power supply.
