A ‘rectifier’ is an electronic device used to convert

A rectifier is an electronic device specifically designed to convert alternating current (AC) into direct current (DC) [1]. AC is characterized by its bidirectional nature, periodically alternating between positive and negative cycles, which makes it unsuitable for many electronic devices that require a steady, unidirectional flow of electricity. The rectification process typically utilizes diodes—often arranged in a bridge configuration—to ensure that current flows in only one direction across a load. While a rectifier converts AC to DC, the reverse process (converting DC to AC) is performed by a device called an inverter [1]. Rectifiers are essential components in power supplies for domestic equipment and industrial applications where stable DC voltage is required from an AC source [1].
