This paper proposed a novel multiplexing module based on LCL topology for dynamic wireless charging of electric vehicles. The LCL compensation network is widely used due to its insensitivity of output characteristics to load variation. But the design of an LCL topology requires a compensation inductor with the same value of a transmitter. The proposed multiplexing LCL module (MLM) can make the primary...

Most of the present EV on-board chargers utilize a three-stage design, e.g., AC/DC rectifier, DC to high-frequency AC inverter, and AC to DC rectifier, which limits the wall-to-battery efficiency to ∼94%. Instead of using the regular three-stage design, a matrix converter could directly convert grid AC to high-frequency AC thereby saves one stage and potentially increases the system efficiency, however,...
