Misalignment-Resilient Copper-Based Wireless Power Transfer

Source abstract and PDF provenance

Excerpt from original “Abstract”

An ordinary-copper, three-mode magnetic-resonant wireless-power-transfer design is analyzed in a cumulative reproducible framework combining Gaussian pose errors, relative AC phase on T 3, solid-torus winding centerlines, and signed parity-inspired transverse windings. The article preserves the earlier reciprocal Neumann mutual-inductance derivations, exact load-matching theorems, Gaussian/thermal and multiport estimates, and explicit negative constraints from parasitic loss and finite switching power. A fixed-count, central-coil-only three-level full bridge admits a new simpler pre-experimental proof that does not require a continuous complex-current optimizer or position sensor. Using an independently reproduced 81-by-81 Neumann grid, a continuum bilinear interpolation theorem, the full −2.6% to +1.8% temperature-range 32-MHz internal-MCU-clock specification, and capacitor quality factors at least 1400, we derive PL,1 > 5.23 W, ηAC,1 > 99.03% and I0,RMS < 1.555 A throughout the modeled [−20, 20]2 mm XY workspace and frequency interval 144.296–150.815 kHz. The ideal pulse waveform is decomposed into all odd harmonics. A passive-circuit current-tail theorem is independent of upper bounds on winding resistance; the stronger ηAC,all > 99.0120% statement is shown only under a separately quantified and unverified upper bound on the effective resistance of every odd harmonic. A reproducible 1,686,177-point electrical stress mesh and the complete analytic continuum proof are presented separately. All hardware dimensions, thermal/electromagnetic and MOSFET losses remain model-specific; no photograph of a manufactured prototype or measured 5-W/99%-DC end-to-end result is claimed. New closed-form interval results further allow independently varying (±2%) physical inductances … [excerpt; full original in PDF]
