FHA Model 01 — Double-Loop Single-M (DL-SM) Hybrid Coupling Circuit: Frequency/Load Sweep

This dataset contains a First Harmonic Approximation (FHA) analytical sweep of the DL-SM (Double-Loop Single-M) hybrid inductive-capacitive coupling circuit topology for wireless power transfer (WPT), derived symbolically with SymPy from the circuit's governing equations, following the modelling approach of B. Pakhaliuk, V. Lysiuk, I. Burmaka, O. Matiushkin and R. Strzelecki, "Simulation analysis of wireless power transfer solutions with hybrid inductive and capacitive coupling" (manuscript, unpublished). Baseline double-loop hybrid topology: L1/C1 form the primary resonance and L2/C2 the secondary resonance, coupled through a single mutual inductance M. DL-SM is one of the six core topologies analyzed in the source paper (Fig. 1: Single M / Additional L / Double M, each in Double- and Single-loop form). The topology belongs to a family of hybrid-coupling compensation variants evaluated for dynamic hybrid WPT systems: six core topologies from the paper (DL-SM, DL-AL, DL-DM, SL-SM, SL-AL, SL-DM), plus extended variants (no-C2, parallel-C2, and LCC-based compensation networks). This record covers DL-SM. Topology abbreviations DL — Double Loop — separate primary and secondary resonant loops SL — Single Loop — one resonant loop spanning both sides, single compensation capacitor SM — Single M — one inductive coupling pair (mutual inductance M) AL — Additional L — extra non-coupled, high Q-factor inductance added in series to shrink C1 DM — Double M — a second inductive coupling pair (M1, M2) added via the additional inductance C2 — Secondary-side compensation capacitor N — (suffix) No C2 — secondary-side compensation capacitor removed P — (suffix) Parallel C2 — secondary-side capacitor connected in parallel instead of series LCC — Inductor-Capacitor-Capacitor compensation network Dataset Structure frequency_sweep.csv — 800 rows (200 frequency points × 4 load points), swept over 50–150 kHz at RL_dc ∈ [1, 20, 50, 100] Ω, Vin_dc = 100 V. Columns: freq_Hz — sweep frequency, Hz RL_dc_ohm — nominal DC-equivalent load resistance, Ω Iin_A_pk / Iin_phase_deg — input (primary) current, peak amplitude (A) and phase (deg) Iout_A_pk / Iout_phase_deg — output (secondary/load) current, peak amplitude (A) and phase (deg) Zin_ohm — input impedance magnitude, Ω Vout_V_pk — output (rectifier-input) voltage, peak amplitude, V Pout_W — output active power, W Efficiency_pct — Pout/Pin, % components.json — the R/L/C and coupling (k, M) values used, tuned to resonate at f0 = 85 kHz. frequency_sweep_plot.png — six-panel overview (|Iin|, phase(Iin), |Zin|, |Iout|, phase(Iout), efficiency vs. frequency) for a quick visual check of the sweep. Intended Uses validation of FHA models against SPICE or hardware measurements, resonant tuning and compensation-network design studies, comparative screening across the hybrid-coupling topology family, input for control-loop or converter-level system simulations, training data for surrogate/ML models predicting efficiency or gain vs. frequency/load. Limitation: results are purely analytical (fundamental-frequency phasor solution); no SPICE, numerical circuit simulation, or hardware measurement was used to cross-validate them.
