some one give me a circuit....


that convert a 12 volts AC to 12 DC,,,,

 

Use a full-wave rectifier bridge then the voltage pulses will be +15V. Smooth and filter the pulses with a capacitor that is calculated for the current. Then use a 12V voltage regulator IC for a current of up to 1A.

You forgot to say how much DC current you want.

 

can you give a circuit.....bro???

 

Let's start you off with out Ebook on rectifiers. Remember that this is supposed to be your homework - do make some effort.

 

i need .80 A

 

Okay - what devices might you need?
