Are You Familiar With This Bridge Circuit?

 bridge rectifier

I believe you have come across such circuit (bridge rectifier circuit and how it works) especially when you study any basic electronic course or reading any theory books on electronics. It is good to understand the circuit/diagram but in the actual repair one have to know about how to accurately test the circuit or component be it off board or on board. A guy who is good in electronic theory could reason with you about how all the current flows in the circuit and etc but when comes to testing the bridge rectifier they are stuck.

So if you really wants to be good in electronic repair make yourself  good in testing electronic components and of course understanding how the circuit works would be an added advantage for you.

    why is it we use a bridge rectifier ckt in most of the applications, why dont we use othher full wave rectifying ckts foe ex a two diode fwc,center tap etc

    Hi Megha,

    The reason to use the bridge rectifier is to produce the desired output but does not require a special centre tapped transformer, thereby reducing its size and cost.

    The Circuit Shown above is Full wave Rectifier Circuit diagram. which is commonly used in every Electronic Equipment.
    there are two types of Rectifier and DC supplies. Such as.
    1. Full Wave and Half Wave Bridge rectifier.
    2. Pure DC and Pulsating DC supply.

    mostly electronic DC Supply and circuits works on full wave bridge rectifier and pure dc supply.

    HI Amir,

    Yes you are right!
