What is the key factor that makes a Full Wave Bridge Rectifier different from a Full Wave Rectifier?

A Full Wave Bridge Rectifier is distinct from a traditional Full Wave Rectifier primarily because it utilizes the entire transformer coil, allowing for rectification to occur for both halves of the AC waveform. This innovative configuration employs four diodes arranged in a bridge circuit, which effectively harnesses the positive and negative halves of the input AC signal.

In a typical Full Wave Rectifier, if it uses a center-tapped transformer, it only taps into one half of the transformer coil for each half of the AC waveform. This limits the output to only half of the transformer’s capacity, whereas in a Full Wave Bridge Rectifier, both halves of the transformer’s coil contribute to the output voltage, maximizing the efficiency and potential output of the system.

This functionality facilitates a more consistent and higher average output voltage from the rectifier, resulting in smoother DC output compared to the alternatives. Hence, the design and setup effectively enhance the rectification process by leveraging the full capability of the transformer.
