Research on Wireless Charging System Based on Double-Sided LCC Compensation Topology

This paper investigates the compensation technology of wireless power transmission for electric vehicle charging, proposes a new LCC- LCC compensation structure for wireless charging topology, and investigates the performance of its topology in detail, and analyzes and calculates the resonance conditions as well as the transmission power expression in the compensation network. A system simulation model based on the LCC - LCC resonant network is established in MATLAB/simulink, and the system's transmitter current and receiver current curves, as well as the output voltage, transmission power and transmission power efficiency curves under the load conditions are obtained through the simulation, which verifies the validity of the proposed compensation structure, and has referential significance for the design of the system based on the LCC - LCC resonant network. The proposed compensation structure is verified to realize constant current charging under resonant conditions, which is of reference significance for the system design based on LCC - LCC resonant network.
