What is a switching power adapter used for

1. The switching power adapter is a kind of power adapter, also known as voltage converter, which is a kind of equipment that uses modern electronic technology and the corresponding control switch to turn on and the corresponding shutdown time ratio to convert the 220V alternating current of the mains into more than ten volts alternating current for electronic equipment or electrical appliances.

2. The switching power adapter is generally composed of full-wave rectifier, switch tube, excitation signal, freewheeling diode, energy storage inductor, filter capacitor and other parts.

3. Switching power adapters are generally used in tablet computers, digital photo frames, humidifiers, air purifiers, electronic refrigerators, LED lamps, LED optoelectronic products, security equipment, massagers, LCD TVs, digital products, medical equipment, monitoring equipment, laptops, home computers, hard disk enclosures, electric vehicle charging, small household appliances, industrial equipment, audio-visual and video cameras; Widely used in electric vehicles, batteries, electric toys, massage and beauty, medical equipment, monitoring systems, instrumentation, vehicle appliances, diving lights, submersible pumps, routers, set-top boxes, switches, instrumentation, mini TVs, handheld computers, network information products, communication products, tunnel lights, fence lights, wall washers, spotlights, magic lights, soft light strips, backlight groups, etc.!

4. The switching power adapter does not use a bulky power frequency transformer, and because the power dissipation on the switching MOS tube is greatly reduced, a large heat sink is omitted, so most of them are relatively mini.
