| description | To address the stability issues of energy and information transmission in wireless power and information transfer system operating over a wide temperature range, this paper establishes a mathematical model of the resonant frequency of an electromagnetic coupling system under varying temperature conditions. Simulations and experiments are conducted to analyze the impact of temperature on resonance characteristics. The results show that within the temperature range of −40 °C to 50 °C, frequency deviation leads to a reduction in the power deviation coefficient to 35.93%. To mitigate this issue, a real-time frequency compensation method based on Direct Digital Synthesis (DDS) is proposed, which dynamically adjusts the operating frequency to ensure that the system remains in optimal resonance. The experimental results demonstrate that the proposed method reduces the system’s operating frequency error from 3 kHz to within 0.2 kHz (a 93.33% reduction), restoring the power deviation coefficient to 0.54% and significantly improving system stability and reliability. This study provides theoretical support and engineering insights for the optimization of electromagnetic coupling wireless power and the information transfer system under wide temperature conditions. |
