This is essentially the same thing that I describe here:
http://www.coe.ufrj.br/~acmq/tesla/sstc.html
The version without a transformer.
But in my case, I look for the particular impedance matching that
causes the impedance seen by the driver to be "maximally resistive",
that is, where in a first-order approximation the impedance continues
to be resistive if the driver frequency changes a bit. As there is
only one solution, a transformer is used to make the actual impedance
transformation, resulting in the typical drsstc structure.
