摘要： Embodiments of this application provide a magnetic element, an inductor, an inductor assembly, and an electronic device. The magnetic element includes a top plate, a bottom plate, a side plate, and a winding structure. The top plate and the bottom plate are disposed opposite to each other at an interval in a first direction. The winding structure is connected between the top plate and the bottom plate, and is configured to wind a winding. The side plate and the winding structure are disposed at an interval in a second direction. The side plate, the top plate, the winding structure, and the bottom plate jointly form a carrier of a magnetic flux loop. The side plate includes a plurality of strip structures that are stacked. A stacking direction of the plurality of strip structures is a third direction.

摘要： A power converter including a drive circuit connected to a power conversion circuit. The drive circuit is configured to: amplify a control signal from the controller, drive a switching tube in the power conversion circuit to be turned on or off, to implement power conversion of the power conversion circuit. The controller is configured to: in response to a voltage of the power conversion circuit being greater than or equal to a first threshold, control the drive circuit to be in a first amplification mode; or the controller is configured to: in response to a voltage of the power conversion circuit being less than a first threshold, control the drive circuit to be in a second amplification mode. An equivalent drive resistance of the drive circuit corresponding to the first amplification mode is greater than an equivalent drive resistance of the drive circuit corresponding to the second amplification mode.

摘要： A photovoltaic converter and a photovoltaic generation system. The photovoltaic converter is configured to electrically connect to a first photovoltaic module and a second photovoltaic module, where the first photovoltaic module includes a first positive electrode output end and a first negative electrode output end, and the second photovoltaic module includes a second positive electrode output end and a second negative electrode output end. The photovoltaic converter includes a current transformer and a power conversion circuit. The current transformer includes a magnetic structure, a first positive primary side winding, a second positive primary side winding, a negative primary side winding, and a first secondary side winding. The three primary side windings all pass through the magnetic structure and are spaced from each other. The first secondary side winding is wound around the magnetic structure. This reduces an occupied board area.
