this last is with the power amplifier and SG3524 pwm circuit together.

Any questions...(++++++++++)

reminds me of my homemade amp.

Very nice design!

 

[Ryssen]

Gerber files of what?

Well maybee the board..

Hi,

I have this SMPS board I ripped from a car amplifier, it uses UC3525. It produces + and - 35Vdc.

Ohh I am very sorry, I didn't realize that this isn't the same tread as where the schema, PCB,.. is.

So here is schema: 1

PCB bottom: 2

And components : 3

The original thread is here
Again I am very sorry.

here is my SMPS for the car sub amp i made

just basic (ESP) design overbuild with 8x (irf540 28A) fets - double discrete rectifier with ultrafast 1000v diodes (MUR8100E) - the usual SG3525 controler - lots of 105C caps and frond and back chokes for filtering - handmade tranny potted with superglue - perforated board constraction with very fat solder tracks and fat cabling - 50Khz operating frequency - dc output +/- 60volts

very pleased with the outcome .
smps exibits some hi frequency harmonics in the 10-15 Mhz region wich does not affect itself or amplifier . and didnot bother to filter more . 6 months in car use driving an overbuilt "A.Holton N-channel amp" with a 4ohm JBL P1220 400Wrms SPL woofer easily up to its x-max with no distortion proved power capability and stability .

here is the big picture . .

 

[tmyr]

and finaly the big idea . .

 

[2pist]

Thats a brilliant idea. nicely done too.

 

[N-Channel]

Definitely an A+ for originality!
