Quick update on this supply. The last iteration with the beefier cores did not operate as expected. The composition of the cores did not provide proper inductance so the system was reverted back to the original smaller cores.

The PSU was a true performer for the fusor it was designed to power.

Being almost a year ago I no longer have the exact specs and they are no longer offered from the seller. The above pic indicates their size. Another issue was the spacing between the primary and secondary. Too close and I'd suspect it'd ultimately break down.

Regardless of all that, the smaller cores were/are the bees knees.

Good Morning,

Hope you are doing well. Hopefully, I am not asking something already on the fusor Q&A or elsewhere but could you provide the calculations conducted to design this power supply?

sincerely,
Yosef Herrera
