Abstract:

For digital power factor correction (PFC) control methods, the duty cycle is calculated in every switching period. One main implementation barrier is the limited switching frequency, due to the limited processor speed. In this paper a predictive digital PFC control method is proposed to solve this problem. The proposed control method generates all the duty cycles in advance, based on the reference current and sensed inductor current, input voltage and output voltage. It requires only one multiplication and three addition operations for digital implementation, so that the proposed PFC control method can be implemented (by using a low cost DSP or microprocessor to achieve high switching frequency). A power factor correction rectifier, can use in mining industry
