Rolf said:Some microwave ovens have a 1uf capacitors rated at 2000v in their klystrons cavity circuit. If that would work then they should not be to hard to get hold of.
the magnetron in a home microwave is too integrated for me to successfully pull apart its capacitor. The voltage doubling capacitor from what i know runs at 50/60hz and not suitable for induction heating.
But i've never seen a Klystron capacitor. Although to be honest i've never seen a klystron. I will look into it though, if this fits the bill i'll use that.
Would a klystron capacitor operate at far above kilohertz levels? sounds like it would run at gigahertz. Would it still be suitable for a kilohertz induction heater?
Roff said:Have you thought about immersing them in transformer oil? I found this interesting thread on the topic when searching for "dielectric oil".
If that oil isn't carcinogenic or toxic then it sounds like a good solution. is immersion all that's needed or do i need to pump it through a cooling system too? if i can find a way to pump it (sounds like it would be highly viscous) then i might consider it. Although if its too expensive and/or bad for human health i'd have to think otherwise.
