Abstract

The invention provides a resonance transformer structure, which comprises a first winding base, a primary winding, a plurality of secondary windings and a magnetic core group, wherein the first winding base comprises a body and a channel, wherein the channel passes through the body; and the body is provided with a first winding zone and a plurality of second winding zones of single grooves; the first winding zone is provided with a plurality of lead pins; the plurality of second winding zones of the single grooves are arranged at the two sides of the first winding zone; the primary winding iswound on the first winding zone of the first winding base, and is connected with the plurality of lead pins; the plurality of secondary windings are respectively wound on the plurality of second winding zones of the single grooves on the first winding base; and a part of the magnetic core group is arranged in the channel of the first winding base. The resonance transformer structure can enhance current transfer power, and reach the purpose of stably controlling a leakage inductance value; and meanwhile, the volume of the resonance transformer is thinned. In addition, the output voltage of theresonance transformer can be increased, thus being high in structure diversity, reducing manufacturing cost, and the like.

Description

technical field

[0001] The invention relates to a resonant transformer structure, in particular to a thinned resonant transformer structure. Background technique

[0002] Transformer is a magnetic component often used in various electrical equipment. It uses the principle of electric energy and magnetic energy conversion induction to adjust different voltages to make it reach the applicable range of electrical equipment.

[0003] In the power supply system of electronic products such as LCD TVs, transformers are mainly transformers with leakage inductance, such as resonant transformers (LLC transformers), to reduce switching losses and reduce noise. see figure 1 , which is a structural schematic diagram of a known transformer. As shown in the figure, the transformer 1 includes a winding base 11 (bobbin), a cover 12 (cover) and a magnetic core assembly 13 (magnetic core assembly), wherein a primary winding 111 (primary winding coil) and a secondary winding 112 (secondary wi...
