Suggestions for sources of gate transformers, rated for 5 to 10kV continuous DC. Or actually, small 1:1 or 1:2 transformers to make simple dc-dc converters for
5kV gate-drive.Will need 100 to 200 pieces, or more. Parts test rated for 5kV for one second, or even for 1 minute, are not acceptable. Maybe parts rated for 15kV for one minute would be good enough. I can design and hand-wind transformers to meet this spec, but sheesh, I don't want to wind 200 or more transformers!
