This electronics video tutorial explains how to build a 12V DC power supply using a 220V AC power source, conventional diodes, zener diodes, capacitors, resistors, and a transformer. The step down transformer brings the 220V AC voltage to 13V AC. The conventional germanium diodes form a full wave bridge rectifier converting AC to DC. The zener diode acts a voltage regulator and the capacitor reduces ripple voltage and converts the pulsating DC wave into a smooth DC output. The series current limiting resistor reduces the surge current that flows through the diode when the capacitor is charging.
