In home electronics, it can be used in commercial controllers, radio communications, and microwave ovens. Its versatility extends to military applications, and to medical devices.

Working Principle

The basic principle of a bridge rectifier is simple. The device is composed of four diodes placed in a “bridge” formation, allowing current to flow in two directions. The four diodes are arranged so that two diodes provide current flow in one direction (forward direction) and the other two diodes provide flow in the other direction (reverse direction).

The VUO62-12NO7 includes four power diodes that are responsible for converting alternating current (AC) to direct current (DC). The diodes alternately “blocks” and “conducts” the current, preventing the current from returning to its source. As a result, the rectified voltage and current can be controlled, with a reduced power loss and minimized interference. The output voltage of the rectifier is determined by the forward drop of the diode and the transformer turns ration (N1/N2).

Conclusion

The VUO62-12NO7 bridge rectifier is a cost effective, reliable, and versatile power solution. With its wide range of operating parameters, it is suitable for many industrial, automotive, electronic, and military applications. Understanding how it works and applying the proper parameters in its use will guarantee successful results.
