dc.description.abstractThis paper deals with a new control method for Power Factor Correctors. Control is carried out by a standard IC controller for peak current-mode dc-dc converters, with only an additional compensation ramp generator and peak detector. Neither an analog multiplier nor an input voltage sensor is needed to achieve quasi-sinusoidal line waveforms, which makes this method very attractive. The method is similar to the one-cycle control method, but can be very easily adapted for use with topologies different to the boost converter, i.e. flyback, buck-boost, SEPIC Cuk and Zeta topologies. Moreover, as the line current is cycle-by-cycle controlled, the resulting input current feedback loop is extremely fast, thus allowing the use of this type of control with high frequency lineseng
