Abstract
In a WPT system, if its system parameters are designed unreasonably, output power and transmission efficiency will be low.Practical WPT must be able to support complicated coil configurations and keep following magnetic resonant conditions with maximum power transfer capability during coupling distance variation.The main parameters affecting output power and transmission efficiency are the distance between the coils, coupling coefficient, the resonance frequency and the resistance of the load.The maximum output power can be obtained in over coupled state by changing capacitor value of the resonating system.The proposed technique is analyzed with an equivalent circuit model, and simulations are performed to evaluate the performance. The system is validated through experimental results.
