Charging principle

Charging principle

We know that most of the civilian rated voltage is 220V, it is not able to directly charge the mobile phone. The use of the mobile phone charger is to convert the high voltage pulse of 220V into a low voltage pulse of 5V, and then go through a rectification and voltage regulator circuit. 5V stable DC power. In other words, the charging base of the mobile phone acts as a function from high-voltage alternating current to low-voltage direct current.

However, plugging the mobile phone charging dock directly into the socket will not generate any current. Only when the mobile phone is connected, the charger will start to work. The current depends on the state of the load: as long as the force is within the range, how much load does it need? Current, how much current the charger provides. If the current required by the load exceeds the current limit that the charger can provide, the charger will always output this maximum current. This is because the protection circuit is usually designed inside the charger. Once the output current is too large, the protection mechanism will be triggered, and the current output will be suspended to avoid danger. That is, even if the charger can output 50A, the inside of your mobile phone. If the charging logic control is 2A, the charging current will still be limited to 2A, and the charging speed will not be affected.
