When used in its most common application, for conversion of an alternating-current (AC) input into a direct-current (DC) output, it is known as a bridge rectifier . A bridge rectifier is a circuit that allows a full alternating current (AC) waveform to pass using a standard transformer and four diodes. Learn how a bridge rectifier converts AC to DC using four diodes in a bridge circuit. Find out its advantages, disadvantages, efficiency, ripple factor, and peak inverse voltage. Learn how a bridge rectifier converts AC into DC using four diodes in a bridge circuit configuration. Find out the advantages, disadvantages, characteristics and applications of bridge rectifier .
