Abstract
A power factor correction (PFC) converter includes an inductor to electrically connect to an alternating current (AC) source, a first set of switches to be electrically connected to a terminal of the inductor at one end and to a negative output terminal at an opposite end, and a second set of switches to be electrically connected to the terminal of the inductor at one end and to a positive output terminal at an opposite end. An output voltage of the PFC converter is between the positive output terminal and the negative output terminal. Two or more flying capacitors are connected between different pairs of adjacent ones of the first set of switches and corresponding adjacent ones of the second set of switches. A controller controls duty cycle of the first set of switches and the second set of switches based on balancing voltages of the two or more flying capacitors.
