摘要: A power factor correction (PFC) system includes an adjustment module, a compensation and duty cycle control module. The module generates N time advances based on predetermined (N−1) advance adjustments, wherein is integer greater than zero. compensated versions of input alternating current (AC) line signal by predicting ahead the AC using gradient sinusoidal reference advances, respectively, synchronized with in phase frequency. PFC cycles signal.
