The development of society and the strength of science and technology are in order to facilitate people's life needs. Various types of electronic devices frequently appear in people's lives. The power adapter is the most familiar accessory. However, at the time when equipment is replaced more frequently, many people's homes, especially those of digital madmen, are simply "piling up" of discarded power adapters. This phenomenon has attracted the attention of the International Telecommunication Union (ITU), and related standards will be issued soon, which deserves the attention of the industry. European power adapter
Reduce the area surrounded by the high-voltage and high-current circuits, especially the primary side of the transformer, the switch tube, and the power supply filter capacitor circuit;
Reduce the area enclosed by the output rectifier circuit, freewheeling diode circuit and DC filter circuit;
Reduce the leakage inductance of the transformer and the distributed capacitance of the filter capacitor;
Use filter capacitors with high resonant frequency, etc.
DC15V output power adapter
In order for the notebook computer to work stably, a stable DC voltage must be provided. This device that provides a stable DC voltage is a DC stabilized power adapter. This DC stabilized power adapter, in addition to providing a stable DC power adapter for the electronic circuit of the notebook computer, is also required to have high reliability, safety and environmental resistance.

There are generally two types of power adapters: one is a switching power supply, and the other is a transformer-type power supply. Switching power supply circuit is more complicated, with more components, it is a new type of power supply. The latter is a very common power supply with relatively simple components, mainly including step-down transformers, rectifier diodes, filter capacitors, etc., and the higher-end ones are also composed of voltage stabilization protection circuits.
