Abstract

The invention provides a U-shaped magnetic core and a transformer, the U-shaped magnetic core comprises two parallel middle columns and a top cover connected with the same ends of the two middle columns, the top cover partially extends towards a direction perpendicular to the plane where the two middle columns are located, and the width of the top cover is larger than the diameter of the middle columns. The top cover partially extends to the periphery of the middle column, the thickness of the top cover is reduced under the condition that the effective sectional area of the magnetic core is the same, the heat conduction path of the middle column is shortened, and the heat dissipation efficiency of the magnetic core is improved.

Description

technical field [0001] The invention relates to the technical field of switching power supplies, in particular to a U-shaped magnetic core and a transformer. Background technique [0002] The high-frequency transformer is the core component of the switching power supply, and the volume of the transformer often determines the volume of the power supply. The output power of switching power supply is constantly increasing, which poses a higher challenge to the power transmitted by the transformer. Usually, multiple transformers are connected in series or parallel or the volume of the transformer is increased to increase the transmitted power. Among them, increasing the volume of the magnetic core can share the magnetic circuit, so it is smaller than the solution of multiple transformers connected in series and parallel at the same power level. The traditional method of increasing the volume of the magnetic core is to use a larger magnetic core, or to use multiple magnetic cor...
