This paper offers a 4-plate built-in capacitive coupler and the model of the system for large air-gap space capacitive power transfer (CPT). The plates in this paper is designated in square and circle types. The four plates are coordinated perpendicularly, and horizontally, to save field in the electric vehicle charging application and make comparison between them. In vertical configuration, the two plates that on the similar region are positioned near to each other to ensure a huge coupling capacitance as well as in horizontal configuration, and a comparison is made between the arrow capacitive plates and column plates and see the result of unlike sizes to uphold the coupling among the primary and secondary sides. The circuit representation of the coupler is approaching, allowing for every one of six pairing capacitors. The Double-sided LCL compensated circuit topology is utilized to resonate through the coupler and supply very high voltage on the plates to transfer high power. The model that belong to the circuit of the coupler is very simple to design the parameters of the compensation circuit. to design the specific parameter values. We use Finite-element analysis to simulate the coupling capacitance and design the size of the coupler. The circuit presentation is simulated in ANSYS to design the precise parameter values.
