In fact, the power adapter is a power converter (i.e. AC to DC), which is converted from AC to DC, and then passes through the computer. It is impossible to maintain the computer, but there is a storage (also known as charging head) for storing power in the computer, so the computer can be maintained during the period of power failure.

The switching power supply is characterized by high-speed channel and stop by operating the switch tube through the power circuit Convert DC into high-frequency AC and supply it to the transformer for voltage transformation, and then generate two or more required voltages! The reason for switching to Huawei high frequency AC is that the output power of high frequency AC in transformer transformer power supply circuit is much higher than 50Hz Therefore, the switching transformer can do little, and the safe operation is not very hot!! The cost is very low Switching power supply is meaningless if 50Hz is not changed into high frequency.
Both switching power supply and power adapter are switching power supply, which are composed of high-frequency switching tube and control power supply circuit. The power adapter is this voltage stabilizing tube switching power supply. The switching power supply contains floating charge function. The voltage increases with the reduction of electric flow, and finally there is no electric flow due to voltage.
Switching power supply is a whole class. The power adapter belongs to switching power supply
In practice, most of the power adapters we touch are switching power supplies. Switching power supply refers to the power supply that controls the time ratio of switching tube application for registration and shutdown through modern electronic technology to maintain a stable output voltage. The switching power supply of power adapter is usually composed of pulse width modulation (PWM) control IC and MOSFET. Its advantages: high conversion output power, light weight and safe operation within a wide voltage range.
