A power factor correction (PFC) system includes a comparison module, an adjustment module, a compensation module, and a duty cycle control module. The comparison module measures N currents having different phases, and generates (N−1) comparisons based on the N measured currents, wherein N is an integer greater than one. The adjustment module determines (N−1) time advance adjustments based on the (N−1) comparisons, respectively. The compensation module generates N compensated versions of an input alternating current (AC) line signal based on the input AC line signal, a sinusoidal reference signal, and the (N−1) time advance adjustments, wherein the sinusoidal reference signal is synchronized to the input AC line signal in phase and frequency. The duty cycle control module controls PFC switching based on the N compensated versions of the input AC line signal.
