Power adapter and switching power supply is different, and their size, shape and size, the accuracy of density, performance and other parameters are different, their application is different. Power Adapter is mainly applied to small appliances, electronics, and switching power to control the entire switch switching current equipment for all electronic devices. The following small series to focus on explaining the characteristics of the power adapter and switching power supply as well as differences.


Feature a power adapter and switching power supply


Switching power supply features:


    The road is to use high-speed on and off by circuit control switch, the direct current into alternating current supplied to the high frequency transformer transformer, resulting in one or more sets the required voltage. High frequency alternating current is converted to high frequency AC efficiency because the transformer in the transformer circuit is much higher than 50HZ, so switching transformer can do very little, and when the work is not very hot, very low cost, if you do not change the 50HZ high frequency switching power supply that does not make sense.


Power Adapter features:


    Power adapter manufacturers of power converters (both AC switch DC), mostly converted from AC to DC, and then through the computer, it is not to protect the computer, but the computer which has the power storage reservoir (also called chargers), so power outages when you can protect your computer.


    Switching power supply and adapter are switching power supply, by the high-frequency switch and control circuit. The power adapter is a regulated switching power supply, switching power supply charger is with float function, with the current voltage is smaller and larger, in the end is not only the voltage and current.
