How does a mobile charger work? SMPS with Optocoupler.
How a mobile charger works:
For reasons of small size, the mobile charger has a different charging circuit from a normal battery charger circuit. Modern mobile chargers work as SMPS (Switch Mode Power Supply). This kind of charger can work at 110v-230v, 50Hz-60Hz. The operation of a simple mobile charger is described step by step below. We have described the operation of the mobile charger circuit which is shown in the image below.
1. Initially, the 220-230v AC power supply passes through the rectifier bridge made up of four diodes then rectified by the rectifier bridge.
2. The DC output is filtered by a capacitor.
3. Then 220-230v DC passing through the two transistors and converted into a high frequency AC signal.
4. The high frequency AC signals are passed through the power factor correction capacitors and the filter again, which increases the efficiency of the circuit.
5. Then the high frequency AC signal from the filtrate goes to the pulse transformer which lowers the voltage to 5v.
6. The 5v AC is converted to DC by a diode.
7. The DC output is filtered by a capacitor.
8. Then, pure direct current is supplied to the mobile to charge the battery.
