Diodes - Bridge Rectifiers

A bridge rectifier is an electric rectifier circuit that typically uses this configuration of four diodes in a bridge arrangement to achieve full-wave rectification. This is a type of half-wave rectifier that produces an output which is an alternating current (AC) that has been converted to direct current (DC).

The GBPC1502M T0G not only uses the four diode bridge rectifier configuration, but also contains a thermal shutdown circuit, electronic surge protection, and a snap-off option for DC-DC applications. This rectifier offers higher performance than standard diode bridge rectifiers with the same size.

Application Fields

Bridge rectifiers are widely used in power supplies, especially modern switched mode power supplies (SMPS) built with transistors. The bridge rectifier provides the DC voltage for the SMPS. Bridge rectifiers are also used extensively on many consumer electronics, particularly televisions and desktop computers. Bridge rectifiers used in consumer electronics are usually enclosed in plastic cases to protect them from the environment.

In power supplies, the bridge rectifier serves to convert the AC input to a low-ripple DC output. In addition, bridge rectifiers are used in sensitive DC power supplies, such as ones used in medical equipment, since they offer better voltage regulation than linear regulators. Bridge rectifiers are also used in voltage regulators, current limiters, and other power conversion circuits.

Working Principle

The working principle of a bridge rectifier is straightforward. It is a circuit with four diodes arranged in a specific configuration. When an alternating current is applied to the circuit, two of the diodes will conduct and two will not, based on the polarity of the supply voltage. When the voltage is applied to the circuit, the two diodes that are conducting will convert the current from AC to DC.

When the AC supply voltage changes direction, the two diodes that were conducting will stop conducting and the two that were not conducting will now start conducting, ensuring that the output voltage is still DC. This process is repeated for every cycle of the input voltage and this is what gives bridge rectifiers their rectifying capabilities.

The GBPC1502M T0G bridge rectifier is a special type of bridge rectifier that offers higher performance than standard diode bridge rectifiers while still being housed in the same size package. It includes a thermal shutdown circuit, electronic surge protection, and a snap-off option for DC-DC applications.

Conclusion

Bridge rectifiers are widely used in power supplies to convert an AC voltage to a DC voltage. The GBPC1502M T0G bridge rectifier is a special type of bridge rectifier which offers higher performance in the same size package compared to standard bridge rectifiers. It includes a thermal shutdown circuit, electronic surge protection, and a snap-off option for DC-DC applications.
