Diodes are considered two-terminal semiconductor devices, and bridge rectifiers belong to a specific type of diodes that have various advantages in the industrial and the automotive engineering; the most important characteristic of Bridge Rectifiers, in general, is to turn the alternating current into a direct current.

The GBU802GTB is one of the modern devices that can be used for bridge rectification – it has 8 pins, and its maximum operating voltage is of 800V. Its advanced features are helpful for obtaining a better performance as an ideal switch for AC to DC rectifying.

There are some specific application fields for the GBU802GTB, and some of them are: inverter, UPS, charger, ACDC power supply, auxiliary power system, etc. But essentially, these devices can be properly used in any kind of application where a bridge rectifier is required.

The working principle underlying the functioning of Bridge Rectifiers is not really complex, but it is important to be known. The functioning of the bridge rectifier starts with the unidirectional flow of current that is triggered by the forward biasing of the semiconductor diodes. In particular, the forward biasing is formed when the rectifier is connected to the AC source, and the cycle of the AC source creates a pulsating forward voltage across the diode bridge.

In other words, the alternating current has to be given to the alternating terminals in order to generate the unidirectional current; and then it can be extracted from the common terminal. This process is usually slightly modified due to the presence of the capacitors and the inductors, which are attached to the terminals for polarity protection, voltage regulation and signal filtering.
