CORRECTION to #3442: with a series blocking diode the reflected loss acts only during the forward charging half-cycle; the "fivefold gain" figure applies to sinusoidal steady state, not diode step charging
Chris Freedom asked (Discord #neuralstan20-testing 2026-09-29) how charging current can run through the secondary when the diode blocks the reverse direction. Answer: it can't. Loop current (secondary → diode → choke → cell → choke → secondary) flows only during the forward half-cycle. The reflected 220 Ω loss (~919 Ω at 2.9 kHz, k ≤ 0.42) applies only in that interval. Once the diode blocks, the loop is open (apart from diode Cj and reverse-recovery charge), so the choke and cell cannot ring as a closed tank and the cell holds its step. The ring seen after blocking sits on the transformer side: secondary magnetizing L with its winding C, diode Cj and switch Coss. That is the ring the primary shunt actually damps, which inverts the claim that "only the choke-cell tank rings".
Per-pulse effect: the resonant half-cycle overshoot factor is d = e^(−π/(2Q)). Q 100 → d 0.984; Q 19 → d 0.922. The step lands at (1+d)·ΔV, i.e. 1.98 vs 1.92 times the gap: a few % per step, not fivefold. The fivefold figure in #3442 is steady-state sinusoidal resonance only and should not be applied to diode step charging. Loss compounds over the ladder and also comes from the reverse-recovery backflow in slow diodes.
