Please help me with a thing called bridge rectifier. i've been reading a lot about bridge rectifiers, but i still can't understand how they work!!!
If you have any ideas that would help me, please let me know. THANK YOU!!!
It's fairly simple. When the bridge source voltage is one polarity, two of the bridge diodes are forward biased and conduct. The other two diodes are reverse biased and don't conduct. When the source is the opposite polarity, the other two diodes are then forward biased and conduct while the first two diodes reverse biased. Thus the output of the bridge is a full-wave rectified signal.
This link with graphics shows a good example of what Carl mentions. You can see how two of the four diodes in a full wave bridge conduct on alternate half cycles of the incoming AC waveform.
