Should you want to licence the design for manufacturing in South Africa for southern Africa markets I would be interested in discussing the opportunity with you.

We have a demand for 400 Hz GPUs but the age of the refurbished equipment available and the shipping weight from Europe or USA are factors in limiting the available product.

I have access to transformer winding and rectifier/converter assembly with enough sheet metal suppliers to be viable.

Kind regards Paul Sabatier

Thanks for the post Kamran - it's always great to hear about other engineer's real projects.

It's a far cry from my current switching psu issues - a DC-DC converter, 6 - 30V in, 12V 5A out. Efficiency is fine - the problem is the huge amount of 100MHz noise - my design is at least 3x better than the control chip manufacturer's demo board but I still get worst case noise pulses of about +/- 500mV.

More work to do ...........
