Bridge Rectifiers are rectifier devices packaged with four diodes in a bridge circuit configuration, and are the most universal AC-DC conversion units in power circuits. Their core function is to achieve full-wave rectification by utilizing the unidirectional conductivity of diodes, converting alternating current (AC) into pulsating direct current (DC). Compared with half-wave rectifiers, they have significant advantages of higher conversion efficiency, lower output ripple and higher transformer utilization. Common types include single-phase bridge rectifiers (the most mainstream), three-phase bridge rectifiers (for high-power scenarios) and integrated bridge rectifier modules. They are widely used in switching power supplies, chargers, frequency converters, motor drives, photovoltaic inverters and various electronic devices requiring DC power supply.
