Page 6 · N=3 asymmetric ripple: two valley depths
Low-resolution native pilot · 400 kHz · 12 V → nominal 1 V / 40 A · three buck legs (different L, split PWM on phase 2)
Heatmap: Fourier model only (12×12 samples). Balls and trajectories: real native ngspice gate edges. White circles: model-predicted wells, not an independent native map.
Native Vout samples with each trace's own 40 µs mean removed; common mV scale and matched physical time. No synthesized waveform.
The R2 local-gradient approach is extended with each stage's own known pulse shape/inductance. Controller inputs: common Vout, its private oscillator, its local harmonic template. No other controller's phase, map coordinate, or basin target is supplied. The first 12ms is a pilot, not proof of universal acquisition or a hardware implementation.
