Charging Process Control of Dynamic Wireless Power Transfer System with Active Rectifier and without Wireless Communication System

In this paper a strategy for charging process control of a dynamic wireless power transfer system is introduced. The control scheme is composed of both transmitter and receiver controls. A current control is employed in the transmitter side in order to control the transmitter current in misalignment condition. In the receiver, a power control is used. According to the power demanded by the vehicle, the control in the receiver, regulates the transmitter voltage using an active rectifier. The operation of the control in both transmitter and receiver is without any communication link between two sides. The behaviors of the quantities of the system in different reference powers, mutual inductances and frequencies are investigated. Furthermore, the proposed control scheme is simulated in order to validate the theoretical analysis.
