Electric field coupling transformer and its manufacture

Abstract

An electric field coupling transformer can be made by connecting two parallel conductor sheets with power source or signal source to create original field before varying voltage, to insert an other or several conductor sheets into the power source field for dividing and so long as the ratio between the electric field space of energy obtained by dividing and original field space being divided can be guaranteed as the same with the of conductor sheets distance under the situation of parallel conductor sheet dividing and to satisfy the transformer ratio relation formula the electric field coupling transformer in accordane with the demands can be obtained. The present invention has the advantages of no transient varying voltage impact, the current limitation and short circuit protection avoiding large area circuit burning and the convenience of maintenance, as well as being used as high frequency and impulse coupling transformer or power source.

Description

technical field [0001] The electric field coupling transformer and its manufacturing method of the present invention belong to the basic electrical components, especially the manufacturing of transformers. Background technique [0002] At present, ordinary magnetic coupling transformers use iron cores and coils, and its structure determines that its volume, weight, shape and installation methods are greatly restricted, which hinders the miniaturization of electronic equipment. Since ordinary transformers use magnetic flux coupling, when the magnetic flux of the loop changes, an induced electromotive force is generated. When the current is turned on and off, the electromotive force is very large, which will cause breakdown and damage to components. This phenomenon adds complexity to the switch circuit design. In order to ensure high-voltage resistance, it is necessary to select high-voltage resistant components, increase absorption and discharge circuits, and so on. Accordin...

Problems solved by technology

There are also researches, hoping to use the gyrator to change the capacitance into an inductive element to form a transformer, instead of the magnetic coupling form, but there are no successful reports.

For example, patent 97198534.0 planar transformer, patent 99100579.1 coreless printed circuit board transformer, patent 99124453.2 transformer with high coupling efficiency, etc. have complex structures, high cost, transient voltage impact, no current limiting and short circuit protection functions, and are prone to occurrence Short-circuit and high-current faults bring inconvenience to the maintenance of electronic equipment
