Abstract In order to reduce the control complexity and utilize the system parameters constraint relationship,two features are founded,i.e. the changes of the resistive load does not affect the loop phase of the transmitting coils;the load changes can be accurately calculated by the transmitting parameters. Based on this,the voltage and the current of the power supply can be monitored for calculating the load parameter.The output voltage of the power supply is regulated in real-time to realize the stable voltage of the load resistance before and after changes.Theoretical and experimental results show that the stable output voltage can be realized utilizing this proposed method,which eliminates the interactive communication between the transmitting side and the receiving side.
