A seawater CPT(capacitive power transfer) system requires a constant voltage output for varying loads, zero phase angle(ZPA), and an optimized voltage for the coupler. The constant voltage output of the system is required for some applications such as batteries and electronic vehicles. ZPA is mainly used to reduce reactive power and decrease the voltage stress on components. Optimizing the voltage on the coupler can reduce losses and improve the efficiency of the CPT system. This paper proposes a CPT system with an LC-CLC compensation circuit topology, achieving constant voltage(CV) output, ZPA, and optimized voltage on the coupler. The design process for the parameters of the LC-CLC compensation circuit topology is proposed, and a prototype with a 50V input and 200W rated power is built with 76.6% efficiency in a seawater environment.
