The type can be a power transformer with reduced voltage, traditional or liquid crystal. The boosting operation of the display is ancient, and the transformers are made by the electronics manufacturer according to the requirements to select the corresponding specifications or types, and the voltage conversion process is stable and the working efficiency is good. The early transformer mainly consists of a winding frame and a coil and a secondary coil which are wound and wound on the winding frame. The winding frame is respectively provided with a plurality of secondary pins for the secondary coil and a plurality of secondary connections _ for connection two: group combination On the reel. Since the primary coil and the secondary coil are heavy == tape covered, it is easy to be due to the quality or assembly of the insulating tape. The leakage inductance is high and the high voltage insulation is poor, and the heat dissipation effect is not good. Later, some people proposed the structure of the secondary coil and the secondary coil J, which solved some of the problems of the above structure. However, it is obviously used for electronic products requiring miniaturization of volume, for example, the quality of liquid crystal is changed:, on the above, therefore, the transformer not only requires voltage conversion. ϋ好 and _ _ small, simple good cooling effect.
