Hello,
I am trying to build an AC Power Adapter and have a few questions regarding its inner workings. At its simplest form I understand that the adapter is simply composed of a step-down transformer, bridge rectifier, and a voltage regulator or filter capacitor, and load resistor. However, I have seen the teardown of Apple and Samsung chargers' adapters and I don't understand why they are very complex. In particular, I am trying to understand the 110-240V input Voltage, 0.5A input current adapter with an output voltage of 5V and output current of 2A. I would truly appreciate it if someone could help me understand the Apple or Samsung or Google AC Adapter with a visual representation of a circuit schematic perhaps.
Thanks
