Dear List,

When designing a homebrew HV power transformer for use as a Tesla coil
power supply, what is a suitable value of VA per cross-sectional square
inch of core?  Also, how many turns per volt per square inch of core?  I'm
assuming 60Hz operation, and "transformer iron" core material.  I'm also
ignoring regulation.  How does "tight" -vs- poor regulation affect the
above ratios?  Does a tightly regulated transformer require more turns per
volt, or less?


Many Thanks,

Greg
