Abstract: In order to solve the problem of power supply for tower monitoring equipment in high-voltage complex electromagnetic field environment, this paper proposes a GaN-based domino relay-type wireless power supply system and configuration method. Firstly, based on the circuit mutual inductance coupling model and finite element simulation, the frequency characteristics and power characteristics of the domino wireless power supply system are analyzed. It is found that by adjusting the load impedance matching and appropriately increasing the driving frequency, the transmission efficiency characteristics and frequency offset characteristics of the system can be effectively improved. And combined with the electric field distribution cloud map, the electromagnetic compatibility of the system is verified. Based on this, a prototype of the GaN-based domino wireless power supply system is built. The test results show that the system can realize high-voltage level, long-distance, high-efficiency wireless power supply, and has good anti-frequency offset characteristics, which provides a reference for the application of wireless energy transmission technology in the field of high voltage equipment power supply.
