Abstract :
A new digital control strategy of parallel duty cycle control (PDC) for power factor correction (PFC) is presented and analyzed in this paper. Based on this new control strategy, the duty cycle determination algorithm includes the current term and the voltage term, which can be calculated in parallel and requires only one multiplication and three additions or subtractions operations in digital implementation. So, as compared conventional digital PFC control methods, the PDC control can achieve higher switching frequency, lower cost, lower calculation requirement and better performance. The simulation and experimental results are provided to verify these virtues as well.
