Something i have never encountered before!

When i feed my small driver 12vdc, it works fine with the expected amount of output. But, when i go up to about 30vdc it seems to short. The mosfets are 400vdc 16 amps, the diodes are FR107 500nsTrr diodes, and i am driving a small LOPT.

Has anyone seen this problem? I can provide more info, but i do not really think it'd help any.

EDIT: Nevermind, the problems where due to an internal capacitor in the LOPT. Going to switch to a different LOPT without the capacitor.
