With the development of society, the power of science and technology is great, in order to facilitate people's living needs. Various types of electronic devices frequently appear in people's lives. The power adapter is the most familiar accessory. However, at the moment when devices are replaced more and more frequently, many people's homes, especially the homes of some digital madmen, are simply "piling up" of discarded power adapters. This phenomenon has attracted the attention of the International Telecommunication Union (ITU), and the relevant standards will be released soon, which deserves the attention of the industry. 24V power adapter
The rated output voltage is the output DC voltage of the power adapter when it is working normally, and it can also be said to be the best voltage output by the power adapter when it works for a long time.
The same brand and various models of laptop batteries and power adapters cannot be used in common, because the capacity of each laptop battery is different. The battery capacity is small, the input power of the power adapter is also small, the battery capacity is large, and the input power of the power adapter is also large. 24V power adapter
There are generally two types of power adapters: one is a switching power supply, and the other is a transformer-type power supply. The switching power supply circuit is more complex and has many components, so 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. The relatively high-end ones are also composed of voltage regulator protection circuits.
The wall-plug certified power adapter switching power supply refers to a power supply that controls the time ratio of switch on and off through modern electronic technology, and the wall-plug certified power adapter maintains a stable output voltage. The switching power supply of the power adapter Generally composed of pulse width modulation (PWM) control IC and MOSFET, the advantages: high conversion power, small size, and can work in a wide voltage range.
