Abstract
One example power factor correction (PFC) circuit includes S first bridge arms, a second bridge arm, and a voltage stabilization capacitor that are connected in parallel, and the PFC circuit further includes an integrated inductor. The integrated inductor includes a magnetic core, S first windings, and S second windings. Second ends of the S first windings are respectively connected to midpoints of the S first bridge arms. A second end of a balancing unit formed by the S second windings are connected to a midpoint of the second bridge arm. The magnetic core includes M+1 first magnetic yokes sequentially arranged in parallel. The S first windings and the S second windings are disposed in spaces formed by any two adjacent first magnetic yokes. Two adjacent first magnetic yokes corresponding to the S first windings are the same, and two adjacent first magnetic yokes corresponding to the S second windings are the same.
