Maximizing Q is not automatically optimal — target robust output within stress limits
At series resonance, V_L ≈ V_C ≈ Q·V_drive, so a higher loaded Q does produce higher voltage magnification. But excessive Q also produces: larger circulating current, narrower useful bandwidth, greater sensitivity to component tolerances, higher insulation/device stress, longer transient settling, and — critically — stronger overvoltage under a light or disconnected load. A no-load mathematical model predicts unboundedly high voltage as losses approach zero; that is not the design target. The correct objective is NOT "maximize unloaded voltage at any cost" — it is "maximize required output under the specified load while satisfying every electrical, thermal, insulation, EMI, and switching constraint." A robust optimum sits on a broad, stable gain region, not an extremely sharp peak that collapses with a small tolerance change. When a sweep just keeps pushing Q or peak_v higher, ask whether it is chasing that fragile theoretical peak instead of a robust operating point.
