Double resonant solid state tesla coil

[RobTheHoff]

So, the igbt bridge system i have going is a 600 volt 300 amp full bridge of cm300 igbt's and i was wondering if a .660uf tank capacitor is too big for my system. The mmc is made out of 2000 volt 1uf capacitors, 2 strings of 3 in series. Thank you.

It is a bit hard to answer that question without a circuit diagram with details of the coils.
The mmc is 0.66uF. How does it relate to the tank circuit?
What is the frequency of operation?
