Abstract
A simple circuit is presented that performs the unity power factor function with low harmonic distortion of the input line current. The circuit is of the resistor emulation type. A description of circuit operation and design parameters are included as well as measured performance. An in depth description of the large signal computer model that was used to verify harmonic current content and control loop performance is presented.Keywords
