Mutual Inductance Detection Method of Magnetic Coupling Wireless Power Transmission System in SS Topology Based on Frequency Modulation and Phase Shift Control

Le résumé fourni par la source

Faults occur from time to time in the magnetic coupling wireless power transmission (MC-WPT) system. When the fault occurs, if the system can detect the changes of various parameters in time, the operator can quickly locate the location of the fault, especially the most important system parameter mutual inductance M. In order to solve this problem, this paper proposes a mutual inductance detection method based on frequency modulation control and phase shift control in MC-WPT system with SS topology, in which frequency modulation control and phase shift control will make the system resonate again, and the mutual inductance M of the system can be obtained by reading the valid values of voltage and current parameters from the resonator of the system. Due to the introduction of frequency modulation control and phase shift control, this detective measurement can be highly accurate.
