System and method for current balancing

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