power suppie again

arold19 · 13th December 2002, 10:03 PM

Hello! I just want to know if this is correct and if it not, can you say me what to do !!!!! This is for the ZenV4.

At the output of the diode bridge, I put 4 capasitor of 20 000uF-50V in parellele with an inductance of 1,8mH-18AWG.

The inductance come from my old 2 way speaker!

thank you !

You put them like this: cap-cap-inductor-cap-cap.
But I dont know if 18awg wire for the inductor will be enough..

Hello arold19,

You can use the circuit that is shown below.

The parts are not critical, and you can use
similar ones if you can't find those from the
schematic, or if you already have similar ones.

Best regards,

Somebody know if I can include without risk my inductor 1,8mH 18AWG in the circuit of the power supplie???
thank you!

My (very old) electronics tables shows that 18AWH wire can carry 8A with a 10'C temp rise.

It also has a resistance of 6.4 ohms per thousand feet. Volt drop is proportional to current (specifically bias current): what's the DCR of your inductor?

Nice one,
David.

I don't know what is the DRC!!! If it is he value of the resistance, if is about 1 Ohm with my multimeter!

But I saw on many project that people use some inductor with a very small wire... like 24 or smaller???

For the bridge, can I take a IN4436???
