Power fluctuation suppression technology of dynamic wireless charging system

In order to reduce the power drop of dynamic wireless charging system at the transmission rail switch, a new coupling mechanism of dual channel dynamic wireless charging system is designed. The dual energy transmission channels are designed based on the LCC-LCC compensation topology. By using the constant current characteristics of LCC-LCC compensation topology, the relationship between system output and loss and two channel coupling parameters is deduced. The design of dual energy transmission channels realizes relatively stable power transmission and improves the anti-offset characteristics and anti-drop ability of the system. Finally, the results of the simulation and experiment verify the feasibility of the two-channel dynamic wireless power transmission scheme.
