Abstract
The invention is suitable for the technical field of transformers and provides a transformer with multi-signal input ports. The transformer comprises five magnetic circuits formed by five magnetic cores. First windings are wound on a first magnetic circuit, a second magnetic circuit, a fourth magnetic circuit and a fifth magnetic circuit. A second winding is wound on the first magnetic circuit and the second magnetic circuit, and a third winding is wound on the fourth magnetic circuit and the fifth magnetic circuit. The second winding and the third winding are double magnetic circuit windings, and the first windings are single magnetic circuit windings. The first windings, the second winding and the third winding are one or a random combination of coil windings, plane conductor windings and printed circuit board windings. No winding is wound on a third magnetic circuit, so that mutual inductance does not exist between the first windings and the second winding and between the second winding and the third winding, the three windings can independently form three transformers, input and output of various different signals can be achieved, and functions of the transformer are expanded.
Description
Technical field
The invention belongs to the transformer technology field, relate in particular to a kind of transformer with many signal input ports.
Background technology
Multiple magnetic circuit transformer is comprised of the multipath magnetic circuit of a plurality of magnetic cores and the winding that is wrapped in successively on a plurality of magnetic circuits.After adopting this multipath magnetic circuit, a plurality of coils of transformer disperse to be centered around on a plurality of magnetic cores, and the heat generating spot of the transformer with many signal input ports is dispersed on a plurality of magnetic circuits, have greatly improved the heat dispersion of single magnetic circuit transformer.
But this multiple magnetic circuit transformer only has an input/output port, can not satisfy the requirement that inputs or outputs simultaneously a plurality of signals.
Summary of the invention
The object of the present invention is to provide a kind of transformer with many signal input ports, be intended to solve that multiple magnetic circuit transformer only has an input/output port in the prior art, can not satisfy the problem of the requirement that inputs or outputs simultaneously a plurality of signals.
The present invention is achieved in that a kind of transformer with many signal input ports, and described transformer with many signal input ports specifically comprises:
Five five magnetic circuits that magnetic core forms;
Described the first magnetic circuit, the second magnetic circuit, the 4th magnetic circuit and the 5th magnetic circuit are wound with the first winding, and described the first magnetic circuit and the second magnetic circuit are wound with again the second winding, and described the 4th magnetic circuit and the 5th magnetic circuit are wound with the tertiary winding;
Described the second winding and the tertiary winding are the double magnetic circuit winding, and described the first winding is single magnetic circuit winding;
Described the first winding, the second winding and the tertiary winding are a kind of or arbitrary combination of coil windings, planar conductor winding and printed circuit board (PCB) winding.
As a kind of improved plan, described magnetic core is U-shaped magnetic core or cylinder shape magnetic core.
There is not the coiling winding on the 3rd magnetic circuit provided by the invention, cause between the first winding and the second winding, there is not mutual inductance between described the second winding and the tertiary winding, these three windings can form separately three transformers, can realize the input and output of multiple unlike signal, expand the function of transformer.
