The working principle of the power adapter

In reality, most of the power adapters we come into contact with are switching power supplies. Switching power supply refers to a kind of power supply that maintains a stable output voltage by controlling the time ratio of switching on and off through modern electronic technology. The switching power supply of power adapter is generally composed of pulse width modulation (PWM) control IC and MOSFET. Benefits: The conversion efficiency is high, the volume is small, and it can work in a wide voltage range. Insufficiency: It is more difficult to repair when a fault occurs, and it will cause greater interference to the power circuit.
