View attachment 141553 Hii everyone .

I want to make a 12v to +/-40v power supply which can supply a power of minimum 680watts for powering my car amplifier.So i've went through many websites for getting a circuit diagram for that. But i've got only 220v AC to +/-40v converter circuit diagram. I've uploaded the circuit diagram which I got.

Can anyone please help me to make a +/-40v 680w power supply from 12v dc(car battery output) by either making any modifications to the circuit diagram which i've uploaded above or by providing a new circuit diagram for my requirent.

Can anyone help me please ...

This thread was split from -- 12v dc to +\-35v dc for amplifier .

I need this 12v battery to 40± positive and negative

Here's a suggestion

The example given is for a 48V input, so it should be easy enough to change to 12V.
