• Why is an AC-DC Converter necessary?
Electricity supplied to homes is typically 100V
or 200V AC.
On the other hand, most electronic devices
operate at 3.3V or 5V DC
3. Some motors and lamps can be driven even with AC voltage, but for motors that
include control circuitry (i.e. MCUs) and lamps that have switched to energy-
saving LEDs, AC-DC conversion is required.
