What is the difference between a switching power adapter and a charger
The electronic devices we need to use in our lives need to be charged, and the devices that charge mobile phones are called mobile phone chargers, but the charger product parameters are generally not printed chargers, but power adapters, which are printed power adapters for the charger manufacturers we usually call. There is still a universal switching power supply in life, but the switching power supply is not often called, so next we know how to define the three.
1. Switching power supply: It is mainly responsible for converting DC electricity into high-frequency pulsating direct current, and then through the transformer step-down to obtain the lowest voltage direct current. The charger is generally to convert the 220V AC power supply into a more suitable DC voltage. Switching power supply is generally composed of four major parts: main circuit, control circuit, detection circuit and auxiliary power supply. The charger is composed of shell, input, output, flexible circuit board, electronic components (capacitor, CPU, single-chip microcomputer, MOS tube, triode, switch tube)
2. Charger: The current conversion device for charging electronic devices, common is the usb charger, basically can charge different electronic products with USB device plug, in the usual name, some people call the power adapter charger, some people also call the charger power adapter. But the power adapter package expansion appliances, the charger does not include the power adapter, and usb charger in the design requirements are still different, usb charger to meet the needs of different frequency bands or different currents, such as the current fire fast charger, to the monitoring camera ball machine router and other equipment power adapter is biased current stability
3. Power adapter: power conversion device, our common notebooks, routers and other equipment are called power adapters. Power adapter small size, energy saving and environmental protection, multiple security protection, long service life, a wide range of applications, the type of power adapter can be roughly divided into: desktop power adapter, multi-channel power adapter, usb power adapter and so on
For switching power supply, power adapter and charger among the three, it is easier to distinguish or switching power supply, power adapter and charger are more difficult to distinguish, the basic contact in life will not distinguish, are called chargers, in fact, according to the different differences in power supply equipment, charger biased diversification, power adapter biased stability, But the power adapter also includes a charger
