Finally finising mine SMPS project for Audio Power Amplifiers, and not only audio, ready for selling.
Is an resonant ZVS SMPS mode, soft switching.
This SMPS will be made custom every client (output tensions and power for amplifier power supply) and will have power from 2500W to 5000W; even I had success of more than 6500Watts peak power on outputs (extracted 34 amps from 220Vac main supply).
It will offer 2 sets of simmetrical +/- outputs with common GND, FIRST,the power outputs ones, the big one until 4500Watts between +/- minimum 50Vdc and maximum +/- 190Vdc, unregulated.
The second one is a maximum 500watts power from +/-50Vdc until +/- 90Vdc, unregulated, power being calibrated by classic 3,15A fuses.
Also it offers some low tensions low current outputs, all regulated, and those are:
One simmetrical output of +/-15 volts,regulated, with common GND of +/- power rails, at max 0,8 amps, for preamplifiers, etc.
Two floating 15 volts,regulated at max 0,8 amps for classD drivers, or something else wich need FLOATING supply.
One 24 volts,regulated, at max 0,5-0,6 amps for fans relais, etc.
One variable output of 7-22 volts, max 0,3-0,5 amps for fan of main heatsink SMPS cooling.

All unregulated outputs, power ones, can be made custom client, until maximum +/- 190 volts, rest ones will be classical as above described.
It have been used only high quality materials and components taken from Farnell, Mouser, Aavid Thermalloy,all brand new.
External dimensions of PCB are:
http://postimage.org/image/ju6wd3eof/
where on upper part the main heatsink exceedes 10mm above PCB, so must be taken 319mm / 220mm dimensions.
Price is between 200 and 300 EURO, depending of output power from 2500Watts and 5000Watts.

Some little presentation movie, to the prototype of 5000Watts, custom made for a client wich demanded +/- 100Vdc at 4500watts, on power +/- rails for amplifiers:
