Bridge rectifiers are efficient AC-to-DC converters that use four diodes in a bridge configuration to convert both halves of an AC waveform into DC output. They eliminate the need for a centre-tapped transformer, making them compact and cost-effective. Widely used in power supplies, battery chargers, and motor control circuits, bridge rectifiers offer high efficiency, stable output, and reduced ripple, ensuring reliable performance in industrial, automotive, and consumer electronics applications. Available in various voltage and current ratings, they support diverse power conversion needs.
