Q:
What new technologies are influencing high voltage power supply design?
10 answers
Answers:
HV DC and associated AC-DC-AC, HV power semi conductor devices; for efficient power transmission, HV Inverter based variable frequency power supplies.
~Ashwani Kumar C, Engineering Consultant, Mumbai, India
Current fed topology - better that ZVS or ZCS safeguards secondary high voltage diodes and does not require secondary high voltage choke.
~Bharat Suji, Research & Development, Bangalore, India
High voltage DC magnetic motors and more.... and solid state power generation stand alone units.
~Shawn S, Research & Development, Toronto, Canada
One example is the vacuum magnetic contactor for 6.6/11kV, instead of using the conventional magnetic contactor. The performances of these particular starters are more efficient and safer.

Ultravolt seems good. I haven't needed to buy one for a long while, so I'm not on top of this.
~Graham S, Engineer, Brisbane, Australia
Don't know - I got an email from one that made ultra miniature supplies that looked interesting, but I would have had to call for a quote when what i wanted to do was look at a price list.
~Peter M, Engineer, Austin, TX
I have not found one that has what i want. Not on the shelf anyway.
