Abstract: Embodiments of the present disclosure disclose a power converter and a related system. The power converter includes a controller and a power conversion circuit. The power conversion circuit is configured to convert an input power of an input power supply into an output power of a load, where the input power supply is an external power supply connected to the power converter. The controller is configured to control on/off of the first switch element, to implement connection/disconnection between the input power supply and the inductive element; and control the unidirectional conduction circuit to be turned on before the first switch element is turned on in the power conversion cycle.

Abstract: This application provides a power converter box used in a photovoltaic system. The power converter box includes at least two power converters, and the at least two power converters include one primary power converter and at least one secondary power converter. The primary power converter obtains status information of a photovoltaic substring corresponding to a secondary power converter, and sends, to an inverter by using a PLC communication module in the primary power converter, the status information of the photovoltaic substring corresponding to the secondary power converter and status information of a photovoltaic substring corresponding to the primary power converter. The primary power converter further receives, by using the PLC communication module in the primary power converter, control information sent by the inverter, controls, based on the control information, an output power of the photovoltaic substring corresponding to the primary power converter.

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.
