Rectifiers are essential electronic components and circuits used to convert alternating current (AC) into direct current (DC). They play a crucial role in power supply systems by enabling electronic devices to operate on stable DC voltage. Rectifiers are commonly used in adapters, chargers, and power conversion units to provide a smooth and usable DC output. Available in different configurations such as half-wave rectifiers, full-wave rectifiers, and bridge rectifiers, they are designed to handle various voltage levels, current ratings, and efficiency requirements. Rectifiers are widely used in consumer electronics, industrial power systems, automotive electronics, and communication equipment, contributing to reliable power delivery and efficient circuit operation.
