Power adapter and switching power supply characteristics and differences
Oct 20, 2016

Switching power supply characteristics:

Is used to control the switch through the circuit for high-speed road through and cut-off, the DC into high-frequency alternating current transformer to provide voltage, resulting in the required one or more sets of voltage. Into high-frequency AC because the high-frequency AC transformer transformer circuit in the efficiency much higher than the 50HZ, so the switching transformer can be done very small, and work is not very hot, the cost is very low, if not 50HZ For the high-frequency switching power supply that does not make sense.

Power adapter features:

Power adapter manufacturers produce power converters (both AC to DC), mostly by the AC to DC, and then through the computer, it can not protect the computer, but the computer has a storage power supply storage (also known as charger), so the When the power failure can protect the computer.
