    What is the difference between the characteristics of the power adapter and the switching power supply?

    The characteristics of the source adapter are: power converter (AC to DC), converted from AC to DC, and then through the computer, it can not protect the computer, but there is a storage device (also called charger) in the computer, so Protect your computer during a power outage.

    The characteristic of the switching power supply is to use the circuit control switch tube for high-speed switching and cut-off. Converting DC power to high frequency AC power is supplied to the transformer for voltage transformation to produce one or more sets of voltages required! The reason for switching to high-frequency AC is that the efficiency of high-frequency AC in the transformer transformer circuit is much higher than that of 50HZ. So the switching transformer can be done very small, and it is not very hot when working! ! The cost is very low. If you do not turn 50HZ into a high frequency, then there is no point in switching the power supply.

    Both the switching power supply and the adapter are switching power supplies, which are composed of a high frequency switching tube and its control circuit. The adapter power supply is a regulated switching power supply, and the switching power supply charger has a floating charging function. The voltage becomes larger as the current becomes smaller, and finally there is only voltage and no current.
