N2 - An alternative control method for a Boost Active Power Factor Corrector (APFC) operating in Continuous Conduction Mode is presented, analyzed and verified by simulation and experiments. The proposed APFC scheme employs average current control to shape the input current. The power level is adjusted by modulating the amplitude of a triangular carrier as a function of the outer loop error signal. The proposed APFC does not require neither line voltage sensing nor an input voltage reference circuitry. The theoretical predictions are well supported by simulation and experimental results. The experimental results demonstrate some improved performance at low power levels as compared to other methods of APFC without sensing of input voltage.
