Geometry Optimization of Wireless Capacitive Power Transfer Plates for Electrical Vehicle

Abstract

In this study we proposed capacitive power transfer (CPT) plate coupler of four-plates using for large distance airgap. We evaluated the effect of square and circular plates. In this study we compared capacitive horizontal plates and vertical plates and find the outcome of different size to maintain the coupling of two plates side. This model coupler circuit is approaching, making an allowance for all coupling capacitors. Highly power transfer (high plate voltage) and resonating coupler have been supplied by using the Double-sided LCLC compensated topology of circuit. The coupler circuit model easy to design the compensation circuit parameters. Analysis of Finite-element is used the coupling to simulate capacitance and choose the sizes of coupler. performance of circuit is simulated in ANSYS to proposal the precise parameter values.
