Regarding disruptive Tesla coils: I've read for years
from various sources that the secondary "rings up" to
achieve high voltage. In my mind, resonant rise was a
given. This seems logical considering the low k
between the primary and secondary. In other words,
several half-cycles ping the secondary, "ringing" it
up to progressively higher potential due to...resonant
rise, right? The disruptive coil doesn't really excite
the secondary with a single massive pulse, but rather
a train of very closely spaced half-cycles. I don't
see why resonant rise should be incompatible with
disruptive coil theory.
