Bridge rectifiers are a type of diode setup used to convert alternating current AC to direct current DC. The GBJ602 is an example of a general purpose bridge rectifier suitable for a variety of applications. In this article, we’ll take a look at the applications and working principle of the GBJ602 bridge rectifier.

Applications of the GBJ602

GBJ602 bridge rectifiers are suitable for a wide array of applications. They are commonly found in power supplies, DC motors, and AC/DC converters. The GBJ602 also has some specific applications, such as light dimmers, DC speed controllers for small motors, and as a particle filter in light dimmers.

The GBJ602 is also suitable for use in audio systems, providing efficient power conversion between AC and DC. It can be found in the power supply circuits of amplifiers, turntables, and other audio components. Additionally, the GBJ602 bridge rectifier may be used as a voltage regulator in some DC electronic systems.

Working Principle of the GBJ602

The GBJ602 bridge rectifier is a four-terminal device made up of four diodes connected in a bridge arrangement, as shown in the diagram below. When connected to an AC power source, this arrangement allows unidirectional current to flow, which can then be used to supply a DC voltage.

The AC sine wave is applied to two of the GBJ602’s input terminals. The other two terminals are connected to the load, which is the device receiving the DC voltage. As the AC voltage increases, the two diodes connected to the positive terminal of the load conduct current in the forward direction, whereas the other two diodes conduct current in the reverse direction, and the diode connected to the negative terminal of the load stops current from flowing.

When the AC voltage decreases, the diodes that had been conducting in the forward direction now stop conducting, and the diodes that had been conducting in the reverse direction now conduct in the forward direction. This ensures that the output voltage of the GBJ602 remains relatively constant and independent of the amplitude of the AC voltage.

Conclusion

The GBJ602 bridge rectifier is a versatile device suitable for a range of applications. It is able to convert AC to DC more efficiently than other rectifier circuits, and its four diode arrangement helps reduce the effects of AC voltage changes. With this device, it is now easier to use AC power sources in a wide range of DC applications.
