Common resonant-transformer design mistakes to avoid in the sweep loop

Seven recurring mistakes in resonant HV transformer design, worth checking a sweep spec against: (1) resonating only the nominal L and C while ignoring parasitic elements that can shift the real operating point considerably; (2) ignoring turns-ratio reflection — a few picofarads on the HV side can appear as a large capacitance referred to the primary; (3) treating all winding capacitance as a single lumped capacitor when distributed winding capacitance actually produces several resonant modes and nonuniform voltage distribution; (4) optimizing at no load — the resonant peak can collapse or shift once the rectifier/load actually conducts; (5) maximizing inter-winding (primary-to-secondary) capacitance — it can shift resonance but directly increases isolation-barrier displacement current and EMI, so it should be kept only as large as needed, not maximized; (6) maximizing Q without checking winding, switch, capacitor, core, or insulation stress limits; (7) optimizing the transformer and the resonant tank separately — they are one coupled system, and the choke's leakage/magnetizing inductance and capacitances must be designed together with the rest of the tank, not independently.
