A conventional Tesla transformer has a primary capacitor and inductor,
and a secondary inductor and (distributed) capacitor. Four reactive
elements, and so a 4th-order system.
A magnifier adds to this a third coil and its distributed capacitance
(L3, C3), and keeps the capacitance associated with the secondary coil
(C2). It has then 6 independent reactive elements, and so is a
6th-order system.

It's common to ignore the secondary capacitance in a magnifier, and
so the currents at the secondary and third coils are identical
(remember that this is a lumped model). Without that capacitor and
with L2 and L3 with the same current, it's just a 4th-order system,
essentially identical to a conventional Tesla transformer.

Studies about the use of magnifier structures in pulsed power
applications lead to the conclusion that the C2 capacitance can't
be safely ignored, specially in a very tightly coupled transformer.
The energy that remains there is never transferred to the output.
A procedure was then developed to the design of the 6th-order
magnifier, that doesn't leave any energy in L1, C1, L2, C2, and L3
when the energy transfer from C1 to C3 is complete.
