Abstract

A spatial electromagnetic field analysis method is proposed by adding variable speed nodes to the circuit topology to estimate the optimal location of multiple mobile high-frequency power supplies at multiple nodes in this paper. In the process of continuous motion, the speed and position of motion affect the accumulated power and loss at the circuit node. At the same time, the transmission efficiency and delay characteristics of the high-frequency mobile power supply will also change with the precise positioning of the mobile power supply and the change of the spatially coupled electromagnetic field. The spatial electromagnetic field analysis method with variable speed nodes is used to divide the circuit topology of mobile high frequency power supply system according to the number of nodes. The continuous motion of variable speed nodes is used to simulate the real-time positioning of multiple mobile high-frequency power sources. By analyzing the real-time variation of the high-frequency electromagnetic field at variable speed nodes, the quantitative relationship between the electromagnetic characteristics of the node space and the speed and positioning of the mobile power supply is established. Finally, the fast optimal positioning of each mobile high-frequency power supply in the continuous moving process is obtained. Compared with the position estimation results obtained by the traditional relation calculation method, when the size is greater than 100, the proposed method can locate the position of multi-mobile high-frequency power supply faster and more accurately, and the circuit efficiency reaches 90%. The simulation results verify the correctness of the theoretical analysis.
