What does a power adapter do? 

Power adapter, also called external power supply, switching power adapter), it is a small portable electronic equipment and electronic power supply device, it is a result of in real life, electronic devices are usually cannot be used directly for household electricity, for home use is 220 v power supply voltage, the voltage of power supply and common electronic products generally required for about 5 v to 20 v.Therefore, the role of the power adapter is crucial (module power supply), especially if you go to the United States and other countries, the voltage is different from our country, then more need of 220V to 110V transformer.With it, we can use these electronic products conveniently and safely.So what does a power adapter do?Power adapters are found in small electronic devices such as mobile phones, liquid crystal displays (LCDS) and laptop computers.Generally, it is composed of a shell, a power transformer and a rectifier circuit. According to its output type, it can be divided into ac output type and dc output type.According to the connection can be divided into plug wall type and desktop type.Used in telephone composite aircraft, game consoles, the language repeater, walkman, pen 636 f70797a686964616f31333365643533 remember this devices in computers, cellular phones, etc.Computer with the power adapter, power adapter is widely used in industrial automation control, military industry equipment, scientific research equipment, LED lighting, industrial control equipment, communications equipment, electrical equipment, instrumentation, medical equipment, semiconductor refrigeration and heating, air purifier, electronic refrigerator, LCD, LED lamps and lanterns, communications equipment, audio and video products, security, computer case, digital products and equipment, and other fields, and in these areas have the effect that cannot ignore.What are the functions of a power adapter?
