18.5v 3.5a 4.8mm1.7mm power Adapter for HP Notebook
As the
Power Supply
in the home is generally about 100v-240v (AC), the power supply in the car and the plane is generally about 12V (DC), but these three commonly used power supply is unstable, can not be directly charged to the laptop, otherwise it will damage the battery and laptop. The laptop needs a stable constant voltage dc power supply. Therefore, the working principle of the laptop power adapter is simple: it is to use the principle of
Switching Power Supply
to transform the unstable power supply into the constant voltage dc power needed by the laptop through the conversion circuit, so as to power and charge the laptop.
It is worth noting that this conversion circuit must have a protection circuit (overcurrent protection circuit, overvoltage protection circuit short circuit protection circuit, etc.) to prevent accidents, to protect the laptop from burning.
