Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformer technology, specifically a high-frequency electromagnetic interference-resistant transformer. Background Technology
[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are a primary coil, a secondary coil, and a magnetic core. Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization. In a generator, whether the coil moves through a magnetic field or the magnetic field moves through a stationary coil, an electromotive force is induced in the coil. In both cases, the value of the magnetic flux remains unchanged, but the number of magnetic fluxes linked to the coil changes; this is the principle of mutual induction. A transformer is a device that uses electromagnetic mutual induction to transform voltage, current, and impedance.
[0003] The high-frequency transformer disclosed in the patent announcement number CN 215896113 U has improved the withstand capability of large current and facilitates efficient and rapid heat dissipation by fitting it in close contact with the heat sink aluminum block, thereby achieving efficient and rapid heat dissipation under miniaturization. However, it does not solve the problems of existing devices lacking electromagnetic interference resistance, which greatly affects the operation of high-frequency transformers, and is also inconvenient to install, with complex structure and high cost. Therefore, we propose a high-frequency electromagnetic interference resistant transformer. Utility Model Content
