  "textContent": "The present disclosure belongs to the field of wireless power transmission technology, and specifically relates to a wireless power transmission system for resonance tracking through low-frequency pulse control. The system includes a power supply, a transmitting end, and a receiving end. The transmitting end includes a compensation circuit including a resonance capacitor and a transmitting coil that are connected in series with each other, the receiving end includes a receiving coil. The transmitting end also includes a bridge inverter. The wireless power transmission system completes resonance tracking through low-frequency pulse control of the bridge inverter, and realizes current self-oscillation through pulse charging of voltage. Compared with a conventional negative resistance self-oscillation manner, the present disclosure does not require additional complex negative resistance design and only needs to change an inverter control signal, so it has lower application cost and makes expansion of system function more flexible.",
