a transformer

Abstract

The invention discloses a transformer, which includes an iron core and a coil winding arranged on the iron core, the coil winding includes a primary winding and a secondary winding; the primary winding is provided with 76 turns of main copper wire, so The diameter of the main copper wire is 27AWG; the secondary winding includes a first feedback winding with 6 turns of the first copper wire, a second feedback winding with 16 turns of the second copper wire, and a second feedback winding with 4 turns of double turns. The third feedback winding with three copper wires, the fourth feedback winding with 8 turns of the fourth copper wire, the fifth feedback winding with 8 turns of the fifth copper wire, and the sixth feedback winding with 16 turns of the sixth copper wire ; Wherein, the diameter of the first copper wire is 29AWG, and the diameter of the second copper wire, the third copper wire, the fourth copper wire, the fifth copper wire and the sixth copper wire is 25AWG. The invention can realize multiple sets of voltage output; multiple feedback windings are added in the secondary winding, which ensures the start-up capability of the power supply.

Description

technical field [0001] The invention relates to a transformer. Background technique [0002] At present, due to the skeleton problem adopted in the prior art, the voltage output mode is relatively single, and the switching frequency cannot meet the ideal requirement of 500KHz. The starting ability of the power supply is limited, and the withstand voltage of each insulation cannot reach more than 2000V. The skin effect is easy to occur at high frequencies, and the current driving ability is limited. The output requirements of individual windings cannot be effectively met at the highest or lowest output loads. In the prior art, due to design reasons, the magnetic flux saturation of the maximum output power of the power supply is unstable; at the same time, when the transformer is working, it is easy to generate heat and cause potential safety hazards. Contents of the invention [0003] The purpose of the present invention is to provide a transformer for the defects of the ...
