Diodes - Bridge Rectifiers

Diodes – Bridge rectifiers employ four diodes arranged in a “bridge” configuration to provide full-wave rectification from an AC signal. In a bridge rectifier circuit, the diodes are connected together in such a way that the four diodes form two pairs of series-connected diodes. A bridge rectifier is used for converting an alternating current input into a direct current (DC) output.

DBLS201GHRDG Application Field and Working Principle

The DBLS201GHRDG is a bridge-connected rectifier, with a maximum voltage rating of 400 volts. This diode bridge is suitable for use in power supplies and chargers, universal-motor equipment, auto parts and more.

The DBLS201GHRDG bridge rectifier works by using a conduction angle of 60 degrees when forward biased and by using 180 degrees of conduction when reverse-biased. During forward-biased conduction, electrons are able to flow from the negative terminal of the applied alternating current to the positive terminal. This causes a current to flow through the circuit and sends voltage to the output. When the reverse-biased conduction occurs, electrons flow from the positive side to the negative side, thereby blocking current and no voltage comes to the output.

The bridge rectifier circuit is made up of four diodes arranged in a \'bridge\' configuration with their anodes and cathodes connected together in such a way that two diodes are forward biased and two are reverse biased At the same time. For example, when the positive terminal of the alternating current input is positive relative to the negative terminal, the two diodes in the top left and bottom right are forward biased and the two in the top right and bottom left are reverse biased. This results in the output voltage at the load being equal to the input.

A typical application circuit employing this bridge rectifier includes a capacitor filter to smooth the DC output, an input voltage source, and a load. The input voltage is applied to the circuit, in order to provide the input signal. It is then rectified by the bridge rectifier and filtered to produce a DC output voltage. The load is then used to draw the output voltage for use in a variety of applications.

In summary, the DBLS201GHRDG bridge rectifier is a type of full-wave rectifier circuit that is used to convert an alternating current signal into a direct current signal. This rectifier is suitable for use in a variety of applications, especially those requiring a 400 volt working voltage. Its working principle involves the forward- and reverse-biased conduction of electrons through the four diodes that make up the bridge rectifier circuit, thus producing a DC output voltage.
