igbts could be used in low freq. coils like the oltc. he was planning to run it
at 6khz i think, and the data sheet on the igbts he is using says they could
switch at frequencys up to 100khz. i read that alot of peak power was needed to
make long streamers. with big igbts you could get alot of power. im pretty sure
a sstc would be a more efficient use of the igbts. if you use a magnifier
arrangement to keep the magnetizing inductances high i think you could get the
same performance as the oltc with 2 of the same igbts. i used pspice to
simulate it and it seemed to work ok.Tesla list wrote:.
