Analysis of Wireless Energy Transmission Model for New Power System Monitoring Network and Communication Nodes

Magnetically coupled resonant wireless power transmission (MCR-WPT) is widely used in wireless charging scenarios for power systems because of its long transmission distance and high transmission power and efficiency. However, for powering multiple electronic devices, existing systems cannot realize compatibility and power independent control. Therefore, this paper adopts Hybrid Modulation Waves Pulse Width Modulation (HMW-PWM) to control multi-frequency and multi-load MCR-WPT system. It can supply power to multiple loads with different resonant frequencies at the same time and independently control the power of the system. We establish a dual-frequency dual-load model, and the simulation results show that the system can flexibly and quickly adjust the operating frequency and output power to achieve adaptive charging of electrical equipment at different operating frequencies.
