Linear peak current mode control: a simple active power factor correction control technique for continuous conduction mode

A simplified power factor correction (PFC) technique for continuous conduction mode (CCM) operated power converters is presented which has the following advantages over conventional peak and average current mode PFC techniques: elimination of the controller multiplier and input voltage sensing circuits; unconditional stability of the current loop; and ease of implementation using low cost standard PWM control ICs (e.g. UC2843). Simulation and experimental results verify the viability of the new controller.
