Abstract
The invention is applied to the technical field of transformers, and provides a multi-winding transformer, which comprises five magnetic circuits formed by five magnetic cores. A first winding is wound on each of a first magnetic circuit, a second magnetic circuit, a third magnetic circuit, a fourth magnetic circuit and a fifth magnetic circuit. A second winding is also wound on each of the third magnetic circuit and the fourth magnetic circuit. Each first winding is a single-magnetic circuit winding, and each second winding is a double-magnetic circuit winding. Each of the first and second windings is any one or any combination of a coil winding, a planar conductor winding and a printed circuit board winding. The mutual inductance of the first windings on the second windings is counteracted through third windings, so that the first windings form an independent transformer, and the second windings form an independent transformer to realize the input and output of various different signals and expand the functions of the transformer.
Description
Technical field
The invention belongs to the transformer technology field, relate in particular to a kind of multi winding transformer.
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 multi winding transformer 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 multi winding transformer, 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 multi winding transformer, and described multi winding transformer specifically comprises:
Five five magnetic circuits that magnetic core forms;
The first magnetic circuit, the second magnetic circuit, the 3rd magnetic circuit, the 4th magnetic circuit and the 5th magnetic circuit all are wound with the first winding, and described the 3rd magnetic circuit and the 4th magnetic circuit are wound with again the second winding;
Described the first winding is single magnetic circuit winding, and described the second winding is the double magnetic circuit winding;
Described the first winding and the second 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.
The present invention offsets the mutual inductance of the first winding on the second winding by the tertiary winding and cancels out each other, make the first winding form separately a transformer, the second winding forms an independent transformer, thereby can realize the input and output of multiple unlike signal, has expanded the function of transformer.
