Hello Everybody,
Anybody has any information of the H bridge rectifier, i need to understand basically how it functions comparing to the full wave rectifier.
Thanks,
Samer

The rectifier with just diodes is usually termed a "passive" rectifier, without any ability to actively control when and how it passes current to the DC side. It typically "gulps" current at the peaks of the AC input waveforms. This does lousy things to the power quality of the system.
The rectifier with transistors as well in the legs can be a "active" rectifier. It is essentially the same as an inverter, but usually acting in "(re)generation" mode. By controlling the duty cycle of the transistors, it can much more smoothly take power from the AC input. Of course, this extra capability and complexity costs a lot more.

There is an "H" bridge configuration with switched diodes that is used to reverse the polarity of the DC applied to the load such as a small motor.
