A new duty cycle parallel control method for AC-DC converter with power factor correction is proposed. The duty cycle required to achieve unity power factor consists of two terms: current term and voltage term. They are calculated directly based on the reference current and sensed inductor current, input voltage and output voltage. It requires only one… CONTINUE READING
