•An AC2DC power supply is built using a transformer and a full-wave rectifier.
•Transformer is used to step down the voltage i/p.
•Rectifier converts AC to pulsed DC.
•A filter capacitor is used to smooth out the pulses.
•Capacitor must be large enough to store sufficient charge so as to provide a steady current supply to the load: RLoadC!!1/f f is rectified signal’s frequency (120Hz).
