[TCML] IGBT High Current Low Voltage TC Primaries

[bartb]

Hi Jim,

I think the closest you will find is the OLTC which Terry Fritz 
developed. Here is a concept schematic:

It might be worth looking at Terry's OLTC info and maybe his SISG work 
as well in the Hot Streamer Temp directory.

I'm not studied on the OLTC concept, but I suspect this is close to what 
your contemplating.

Take care,
Bart
