Abstract An improved algorithm for Boost power factor correction(PFC) is proposed. In PI control of voltage loop, although the crossover frequency increases, input current is not disturbed by the secondary ripple in the output voltage, the dynamic response to load variation is also improved. The parameters referred in this algorithm are analyzed and calculated in detail in this paper, by simulations in digital blocks of PSIM software, the effectiveness of this algorithm is verified.
