A Flat Transformer with Unbiased Voltage Push-Pull Circuit

Abstract

The present invention provides a planar transformer with an unbiased magnetic voltage push-pull circuit, which includes a planar transformer body, and the planar transformer body includes a main power transformer T2, a first primary winding N1, a second primary winding N2, a third The secondary winding N3 and the fourth secondary winding N4; one side of the main power transformer T2 is connected to the first primary winding N1 and the second primary winding N2; the other side is connected to the third secondary winding N3 and the fourth secondary side winding N4; the equivalent capacitor C1 is set in the body of the planar transformer; the planar transformer has a simple structure, is easy to operate, has good consistency, is convenient for product miniaturization, and improves product reliability. The internal design is effective for internal Data is kept confidential.

Description

technical field [0001] The invention relates to the technical field of flat-panel transformers without bias voltage, in particular to a flat-panel transformer with a push-pull circuit without bias voltage. Background technique [0002] At this stage, the push-pull topology circuit has the problem of transformer bias, which makes the circuit topology reliability lacking. At present, the bias phenomenon of the transformer is used as the bias magnet of the transformer by connecting an external capacitor on the transformer, but this design occupies the transformer's bias. space, so that the data of the external capacitor is exposed outside the transformer, which cannot achieve the effect of confidentiality. SUMMARY OF THE INVENTION [0003] Aiming at the problems that the external capacitor of the transformer in the prior art cannot make the product miniaturized in terms of volume and the data of the external capacitor is exposed outside the transformer, which cannot achieve t...
