The history of the construction of the charger evolution
2022-08-19      Views:28

Cell phone chargers have evolved from linear chargers to switch chargers to 5V chargers, then to fast charging era, and now to the most fresh and popular gallium nitride. Gallium nitride products are much smaller in size than ordinary chargers, and most importantly, the power is much larger.


The power of the charger has increased more than 10 times, but the volume has been reduced by nearly 1 times, how to do it?


BON manufacturers take you to understand the working principle of the cell phone charger, when you plug the phone charger into the socket at that moment, the socket 220V AC will first enter the charger internal high-voltage area, at this time if you plug the phone, this 220V will be transformed through the transformer into low-voltage AC current into the low-voltage area and then through the diode and other components into the phone can receive low-voltage DC, so Cell phone charger is actually a voltage and current conversion system.





With the continuous progress of the times, the capacity of the battery from the black and white screen era of 450mAh to 800-1000mAh, obviously the linear charger charging power is not enough, so the switch charger came into being.


Based on the linear charger a rectification and switching system is added to the front of the transformer. The general working principle is to convert 220 standard voltage AC into high voltage DC, and then to form high frequency AC by switching on and off at high frequency. So in the output of the same power, the original linear charger in the transformer volume can be significantly reduced, so the volume has become smaller, the power has also increased.
