Introduction to Diodes - Bridge Rectifiers

A diode is an electronic device that has two distinct terminals which allows electrons to flow through it in one direction only. The process of converting alternating current (AC) to direct current (DC) is known as rectified. In this process, a circuit of components is required to facilitate the conversion of alternating current to direct current, such components are called bridge rectifiers. A bridge rectifier is composed of several diodes specifically configured in a bridge arrangement; it rectifies the AC to provide a DC output.

What is a BR3504W-G Bridge Rectifier?

BR3504W-G is a four-terminal bridge rectifier, specifically designed for switching power supplies, AC to DC converters, DC to DC converters and general purpose rectification. It consists of a full-wave rectifier with an anode and a cathode and two special power terminals, A and B. These two terminals offer superior heat dissipation, making it an ideal choice for applications with high power dissipation.

Applications of BR3504W-G Bridge Rectifier

The BR3504W-G is a full-wave bridge rectifier with 4 terminals, and it is ideal for applications that require high power dissipation and high current handling. It is mainly used in power supplies, AC-DC converters, DC-DC converters, and other rectification purposes. The bridge rectifier is commonly used in applications such as power relay, power factor correction, power supply, inverter, high current pulsing, and motor speed control.

Working Principle of BR3504W-G Bridge Rectifier

The BR3504W-G bridge rectifier converts AC input to DC output. It works by connecting the two diodes in series, where the anode of one diode is connected to the cathode of the other diode. This configuration results in a two-dimensional circuit which is symmetrical, but is non-linear. The two power terminals (A and B) provide superior heat dissipation making it an ideal choice for applications that require a high current handling.When the alternating current input is applied to the bridge circuit, the current flows through one of the four diodes. This is known as "Forward Biased". During the alternate half cycles, when the current flows to the opposite directions, the other two diodes are activated. This is known as "Reverse Biased," and helps to ensure a smooth current flow and uniform voltage regulation.

Conclusion

The BR3504W-G is a full-wave bridge rectifier that enables an AC input to be converted into a DC output. It is mainly used for applications requiring a high current handling, such as power supplies, AC-DC converters, DC-DC converters, and other rectification purposes. Its unique power terminals (A and B) provide better heat dissipation, making it an excellent choice for power rectification applications. The two-dimensional non-linear circuit of the bridge helps to ensure a smooth current flow and uniform voltage regulation; hence, making it an ideal choice for higher power applications.
