Power supplies aren't my speciality by any means so thought I'd ask here for some ideas...
I'm looking at playing around with some Class D amps (most likely Hypex-based) for use in car audio. So I need as an example, +- 50V DC power rails.
Easiest solution but not elegant and not DIY and probably the least efficient: use an inverter then a normal 230V AC SMPS to give me the required voltages.
Second easiest solution but relatively costly, buy something like the Coldamp CPS80, but it's out of stock, and I would prefer a self-build.

Hi,
Why buy modules not intended for cars when clearly modules for
cars with their own switching supplies must exist ? (I'm no expert).
rgds, sreten.

Of course, I could get a commercial car audio amplifier off the shelf. But I'd need this to fit in a specific case so thought building / assembling something myself will allow more freedom.
I doubt I'd need 800W RMS either!

Ooh I hadn't realised there was an ESP project covering this - Switchmode Power Supply For Car Audio
