Formulas for Audio Amp PSU requirements
« on: January 30, 2017, 09:20:45 PM »
Hi all,

Not sure if there is a central place for formulas on this forum, did search but could not find info needed.

I am looking for the formulas to calculate power supply requirements based on amp output and speaker impedance, or am I over simplifying things?

Your help will be greatly appreciated

It's not 100% as simple as that because it depends on the architecture of the amplifier,  but its not too difficult.

Start here:

And then you can read a bit on my website here:

I've never seen a more comprehensive and simply-explained summary of all thing power supply.  Thanks for this, I'm bookmarking it and going through it in my spare time now!
