  Small AC to DC Converter

  Posted in: Projects, Starter Projects

  2563 Views

  The small AC to DC Voltage Converter project uses four diodes to make one bridge rectifier to transfer AC power to DC power. Also, we use capacitors to remove ripples in the circuit. After we transfer from AC power to DC power, we need to use one 5v voltage regulator to give 5v DC output from 12 v DC output.
