Definitions

  • the present invention relates to a power supply device, and particularly to an improved transformer, which has a reduced volume and weight, improved efficiency, reduced power consumption, and reduced cost.
  • Power supply devices are commonly used in electronic and electrical products. For example, AC power is rectified and stepped down to DC power. As the driving power of electrical appliances, this is the case for transformers such as household appliances. Transformers are usually bulky and bulky, and are used as power supply devices. Plug-in transformers, or voltage conversion devices inside electrical products.
  • FIG. 1 is a cross-sectional view of a conventional transformer 1 and a part of its casing.
  • This type of transformer 1 has a long history of use. At present, almost all transformers supplied with commercially available transformers or electrical products are For one type, it seems that the transformer must have a considerable volume and weight in general traditional concepts. When users insert the transformer into the jack, they can also notice that the transformer occupies a large area of the socket, which is cumbersome and abnormal compared to ordinary plugs. For the sockets with closely arranged jacks, sometimes the area of the two pairs of sockets of the sockets is even occupied, which causes inconvenience both in use and carrying.
  • This traditional transformer not only has a volume and weight that is disproportionate to ⁇ ’s increasingly thin and short electrical products (sometimes, the transformer product is larger than the product), but its efficiency and power consumption without load need to be improved.
  • traditional transformers The surface is hot, which is the result of the loss of heat from the power conversion, which wastes a lot of energy consumption.
  • the volume of the traditional transformer is huge, mainly because the internal coil 2 takes up most of the volume and weight, and consumes a lot of it.
  • the materials include coil 2, core 3, etc. Strictly speaking, this is not economical. Summary of the invention
  • an object of the present invention is to provide such a power supply device, Used to change AC mains to DC, its volume and weight are small, and its efficiency is improved.
  • Figure 5 is an embodiment of a circuit diagram of the present invention.
  • the above-mentioned power supply devices of the present invention all use mains power input and direct current voltage output as driving power for electrical products, except that the volume and weight are greatly reduced, and the power consumption of such a transformer is also improved on the circuit
  • the phenomenon of electric heating can completely seal the internal circuit with epoxy resin (EP0XY) or other good insulation and moisture-proof materials, so that the entire transformer becomes a whole. Improve the life of the product and the performance of leak-proof insulation, moisture resistance and voltage resistance are greatly improved.

Abstract

Dispositif d'alimentation en énergie comprenant un corps principal et une partie circuit. Le circuit est scellé et isolé dans le corps principal avec un transformateur, sous forme d'ensemble entièrement intégré. La partie circuit comprend une borne d'entrée de tension alternative classique et une borne de sortie de tension continue. Un circuit de redressement redresse la tension alternative d'entrée à fréquence classique. Un stabilisateur de tension attaque un circuit oscillant pour engendrer des signaux carrés à haute fréquence. Les signaux carrés traversent la bobine à courant induit dans un circuit à induction, et une tension alternative de fréquence élevée est fournie par l'étage de sortie de la bobine en question. La tension alternative de fréquence élevée est redressée en tension continue par le circuit de redressement et appliquée à la borne de sortie. Le volume et le poids du dispositif sont considérablement réduits.
