Abstract
This paper proposes a dynamic CPT system LC compensated with a six-plate capacitive coupler to charge electric vehicles in motion. Due to using a six-plate coupler, the electric fields emission to the environment around the coupler declined, which is safe for individuals around the coupler. This system is safe for drivers, and also with regard to the 150mm of the air-gap distance, this system could cover a wide range of electric vehicles. Capacitive power transfer (CPT) is an effective technology to transfer power wirelessly via high-frequency electric fields. Maxwell software is used to design the capacitive coupler and also for simulation of electric fields emission to the environment around the coupler. The fundamental harmonics approximation (FHA) is used for analyzing the circuit performance. This system achieves 261W output power with 90% efficiency.
