The Compensation Research of Contactless Electrical Energy Transmission System

Contact less electrical energy transmission (CEET) system realizes power transmission with no electrical or physical connection by the perfect combination of inductive coupling technique and electronics. This paper studies the characteristics of the CEET system based on the loosely coupled transformer mathematical model, then analyses the power transmission performance and its changing rules in different compensation topologies. We can get the parameter requirements when the load obtains the maximum transmission power from these studies. This work can provide reference to optimize the circuit design and promote the power transmission ability for the CEET system.
