How Full-Wave Bridge Rectifier Works

Transformer receives 120 volts AC input voltage from your household AC outlet. The 120 volts is then converted (or transformed, hence the word transformer) into a lower voltage value (8.5 volts) that will convert to 12 volts DC after passing through the bridge rectifier circuit. The bridge rectifier circuit is primarily a a set of rectifier diodes connected like a diamond shaped loop such that the AC current will flow through two of the diodes during first half-cycle of the AC current and through the other two dioedes during the next half-cycle. The electrolytic capacitor ensures that the output DC voltage that is now coming from the bridge rectifier circuit is a smooth or near-smooth non-fluctuating DC signal.
