Adaptive wireless power charging system

There are two novel techniques in the research of wireless power transfer (WPT), i.e. bidirectional WPT and bidirectional data transmission. The bidirectional WPT allows vehicles to be charged and provide charge to other accepting objects; the bidirectional data transmission allows the WPT system charging without any additional communication device. Both of them are sensitive to the induction coil alignment. Due to the misalignment between the transmission coil and the receiver coil, the output power will result in a drop. The misalignment problem affects the power transmission efficiency significantly. This paper combines bidirectional wireless power transfer with bidirectional data transmission, and constructs a complete bidirectional charging system through a fuzzy control strategy to resolve the issue.
