FFT-FCA based Inductive WPT system for Effective coupling with high Air-gap on EVs Charging applications

Inductive based wireless power transfer (Inductive WPT) system has been approved to be expedient and consistent interface for power transferring in electric vehicle (EV) applications. This method is generally considered by maximum effective coupling, high power transfer efficiency and output power at High Air-gap. This Inductive WPT system can help to precede, optimize, and assess its performance among the progress. It reduced the traditional charging method and its effects on the charging environment. The proposed Inductive WPT design has been classified according to the power transfer air gap amid primary and receiver coils and the oscillating frequency. The effects of primary side issues, magnetic interference can be addressed by harmonic filters and it’s fixed by control algorithm. This paper presents a novel control design and harmonic extraction method as "FFT based Falconry control algorithm (FFT-FCA)". This paper, the FFT-FCA has optimized in the system to hunting the precise current and operating frequency for improving the effective coupling on inductive WPT. This proposed system acumen the perfect coupling for maximum Power Transfer Efficiency (PTE) 90% and high Air-gap (30cm) between coils.
