Transformer

Abstract

The invention discloses a transformer which comprises a magnetic conductive core and an electric conductive part, wherein the electric conductive part comprises a first conducting plate and a second conducting plate which are mutually stacked and electrically insulated; the magnetic conductive core is wrapped by the electric conductive part; the magnetic conductive core is wrapped by the first conducting plate by over one circle; and the magnetic conductive core is wrapped by the second conducting plate for over one circle.

Description

technical field [0001] The invention relates to a transformer, in particular to a transformer with reduced leakage inductance. Background technique [0002] When electricity is used, various voltages are usually used to perform different tasks. For example, when a power plant intends to transmit electricity to a distant place after generating electricity, the voltage will be increased to tens of thousands of volts. When electricity is to be transmitted to the home, the voltage will be reduced to various voltage values ​​such as 220 volts, 110 volts or 100 volts according to the type of power usage and the laws and regulations of various countries. When the electronic device is to be used, the power must then be stepped down to various voltage levels. At this time, a transformer is often required for voltage conversion. [0003] The transformer generates magnetic force by inputting electric power to the first coil, and then guides the magnetic force to the second coil by t...

AI Technical Summary

Problems solved by technology

Such a transformer will have a large gap between the first coil and the second coil, so that the degree of coupling between the two is not good, and a large leakage inductance will be generated

And when the leakage inductance is large, the voltage conversion efficiency of the first coil and the second coil is poor

Moreover, when the high-frequency switch is cut off, the surge voltage will be larger
