A Quasi-Resonant System for High-Frequency Trans-Spinal Magnetic Stimulation (HF-TSMS).

ABSTRACT:

Objective

We designed, developed, and tested a novel non-invasive system for high-frequency (HF) trans-spinal magnetic stimulation (TSMS).

Methods

The system is based on a quasi-resonant pulse width modulation (PWM) design with customizable parameters, coupled with a custom figure-8 coil optimized for selective stimulation of spinal fibers. A key innovation is sequence-controlled zero current switching (SCZCS), which minimizes switching losses.

Results

Through quasi-resonance, a capacitor bank canceled the coil inductance, enabling the generation of 5 kA current pulses at 10 kHz with input voltages over three times lower than traditional magnetic stimulation methods. Preliminary rodent experiments, including electrophysiological recordings from the common peroneal ner
