Abstract: A magnetic component is disclosed and includes a circuit board and a magnetic core set. The circuit board includes two through holes passing through a first surface and a second surface thereof. The magnetic core set includes an upper magnetic cover and a lower magnetic cover disposed on the first surface and the second surface, respectively. The upper magnetic cover includes two magnetic columns connected to the lower magnetic cover through the two through holes. The upper magnetic cover is thermally coupled to a heat dissipation device, and a volume of the upper magnetic cover is greater than that of the lower magnetic cover. A thermal resistance defined from the upper magnetic cover to the heat dissipation device is smaller than that defined from the lower magnetic cover to the heat dissipation device. It helps to make the overall heat distribution of the magnetic component more uniform.

Abstract: The present disclosure provides a power converter including a transformer, a first current detection circuit and a rectifier circuit. The transformer includes a primary side winding and a secondary side winding coupled to each other. The first current detection circuit is electrically connected in parallel to the secondary side winding and includes a first auxiliary winding, a first switch and a first impedance device electrically connected in series. The first auxiliary winding is coupled to the secondary side winding. The rectifier circuit includes a first bridge arm and a second bridge arm electrically connected in parallel. The first bridge arm includes a second switch and a third switch electrically connected in series, and the second bridge arm includes a fourth switch and a fifth switch electrically connected in series.

Abstract: The disclosure can provide a method, an electronic device and a storage medium for displaying a video. The method includes: displaying a first video through a first video region in a display interface; obtaining display parameters of a comment region in response to an operation of triggering to display comments on the first video; zooming out the first video region to a second video region based on the display parameters of the comment region, such that the comment region is displayed in a region outside the second video region in the display interface; and displaying a second video through the second video region; in which the second video is obtained by zooming out the first video; video images in the second video includes key content of video images in the first video.
