Hello, ive got a nice little amp that needs a ~500w dual rail supply ( has a -60v output, a 0v “virtual ground” output, and a +60v output)
Does anyone know of a relatively simple circuit to take my 12v and split it to a 60v, 0v, 60v output? preferably with soft startup and control feedback? have a milling machine, so can etch pcbs pretty well.
I have seen a few designs that use the tl494 that look good, however im not very confident with transformers so it really handy if you recommend a transformer with said schematic (or, i dont mind winding one)

I guess, you mean 120Volt to 2 x 60. If so..... Your headline is mispelled tooto take my 12v and split it to a 60v, 0v, 60v
No, it is a step up circuit, the input is 12v, which would likely oscillate through a transformer with a primary and dual secondary, outputting 60v, 0v, and -60v. The title lacks info.
Yes, it will be used in a car to make use of a 12v battery, and supply a dual rail amp that needs 55v, 0v and -55v

It is clearly a car amp power supply, what else?

besides the 500W requirement that isrelatively simple circuit to take my 12v and split it to a 60v, 0v, 60v output? preferably with soft startup and control feedback
Only if they are 500 W PMPO. If they are 500 W(RMS) they will deliver. Actual PMPO does not exist in the real world. It is a theoretical construct.No. Chinese 500 Watt are in reality only about 50 Watt continuous.
Thanks for the help everyone, i gave up on 12v to dual rail thing, as everyone said it is a little complicated for me at the moment. Found a bargain toroid transformer that can handle 600w and has dual secondaries, so ended up just milling a rectifier and wiring up to the transformer, then printed a amp case. I have a great home subwoofer amp now though which is nice
Hello, I have the same issue for powering up a small 4 channel amp that I develop, I am just letting you that also didn't receive any good recomendations and at the moment I am already decided to design and build an SMPS from 12 to split rails, although it will be for plus and minus
30 volts.
