Abstract
The utility model discloses a transformer with high safety factor, which comprises a magnetic core, a plurality of primary windings P arranged in series and a plurality of secondary windings S arranged in parallel, wherein the magnetic core is positioned between the primary windings P and the secondary windings S, the secondary windings S are arranged between the two primary windings P, and the two secondary windings S are separated by one primary winding P; therefore, the peak voltage is effectively reduced, the comprehensive performance of the power supply is improved, and the cost is optimal.
Description
Technical Field
The utility model relates to a transformer, especially a transformer that factor of safety is high.
Background
The power transformer is a core device in the voltage converter, and the quality of the transformer directly determines the reliability, the consistency and the comprehensive cost of the product; when the output current of a power supply is large, the power exceeds 65W or a product works under the limit condition, the leakage inductance peak generated by the transformer can be obviously increased, the voltage resistance, the temperature rise and the reliability of a power device can be directly influenced, and the increase of the peak voltage can cause a series of problems of the increase of the power consumption of an absorption circuit, the increase of the temperature rise, the reduction of the efficiency, the increase of parameters of the power device, the increase of the cost and the like.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a transformer that can effectively reduce peak voltage's factor of safety is high.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a transformer that factor of safety is high, includes magnetic core, the parallel secondary winding S that sets up of the primary winding P and a plurality of that sets up of a plurality of series connection, the magnetic core is located between primary winding P and the secondary winding S, and the secondary winding S sets up between two primary windings P, separates through a primary winding P between two secondary windings S.
There are three primary windings P and two secondary windings S.
The utility model has the advantages that: compared with the prior art, the utility model changes the winding distribution and winding process of the transformer to reduce the leakage inductance; thereby effectively reducing peak voltage and improving the comprehensive performance of the power supply; and the cost is optimal.
Drawings
The present invention will be further explained with reference to the drawings and examples.
FIG. 1 is a schematic diagram of the present invention;
fig. 2 is a winding distribution diagram of the present invention.
Detailed Description
Referring to fig. 1 and 2, a transformer with a high safety factor comprises a magnetic core 1, a plurality of primary windings P arranged in series and a plurality of secondary windings S arranged in parallel, wherein the magnetic core 1 is located between the primary windings P and the secondary windings S, the secondary windings S are arranged between two primary windings P, and the two secondary windings S are separated by one primary winding P.
The number of primary windings P is greater than the number of secondary windings S.
Compared with the prior art, the winding distribution and the winding process (structural arrangement of the windings) of the transformer are changed to reduce the leakage inductance; thereby effectively reducing peak voltage and improving the comprehensive performance of the power supply; and the cost is optimal.
In order to reduce the peak voltage (by 1 to 200V) to the maximum, the primary winding P is preferably three, and the secondary winding S is preferably two, so that the transformer with the structure is safer.
The above embodiments do not limit the scope of the present invention, and those skilled in the art can make equivalent modifications and variations without departing from the overall concept of the present invention.
