If you supply the power (AC) across the bridge rectifier, the terminal–A turns into positive, and the terminal–B turns into negative during the positive half cycle. Now, We will discuss how a Bridge Rectifier works: The following figure shows the current flow during the negative half cycle: The following figure shows the current flow during the positive half-cycle: Similarly, the diode pairs D 2 and D 4 conduct electricity during the negative half cycle. The diodes that pair to conduct electricity through the positive half cycle are D 1 and D 3.
That is why only two diodes conduct electricity throughout every half cycle. The arrangement of four diodes is made in a unique fashion. Point-C and Point-D are the output terminals that produce DC signals across the load resistor R L. Point-A and Point-B are the terminals where the input signal is applied. The diagram given below shows the circuit diagram of the bridge rectifier: It helps to reduce the cost and size of the device.
The non-existence of the exclusive centered-tapped transformers make the configuration of this device more relevant. Then, it manages to convert the AC (alternating current) into DC (direct current). For making its performance more efficient, these four diodes are linked in a closed-loop configuration. The bridge rectifier includes four diodes, such as D 1, D 2, D 3, D 4. Let’s learn about the bridge rectifier in brief, especially about bridge rectifier working, it’s efficiency, and so forth. To improve the output of the bridge rectifier, a filter is also used inside the circuit. We call it a bridge rectifier as it makes a bridge-like circuit by including 4-diodes. The power conversion in this device is very efficient. It is the most resourceful rectifier circuit from others. The purpose of the bridge rectifier is to convert the AC power into the DC power. Bridge rectifiers are widely used for supplying power to various electronic basic components. The bridge rectifier is said to be widely used circuits among many electronic circuits.
