Abstract: This application discloses a switched-inductor power converter, a communication system, and a method. The switched-inductor power converter includes a coupling winding and a unidirectional conduction circuit, and the coupling winding and the unidirectional conduction circuit are connected in series to form a closed loop. A leakage inductor is formed after the coupling winding and a power inductor are magnetically coupled. Existence of the leakage inductor and the unidirectional conduction circuit may suppress a reverse recovery stress of a first diode, to further reduce a reverse recovery current of the first diode, and reduce a reverse recovery loss of the first diode.
