Another possible solution is to make a separate power supply with each
transformer and put the outputs in series adding. The upper transformer must
be able to withstand the higher voltage without arcing. Usually requires
isolating the core from chassis. About 30 years a company did that with
several 750 volt power supplies to provide 3000 to 4000 volts output. They
would a special transformer for the highest 2 supplies.
