Self -correction algorithms used in performance optimization of wireless battery charger

This paper focuses on wireless power transfer based on Witricity technology, specifically wireless battery charger application for electric vehicle. In order to reach efficient power transfer, a principle of coupling magnetic resonance at high frequency is used. However, in high range frequency, several losses may offer such as peak power, switching losses as well as reducing the size of the required battery capacity. In order to avoid the battery's damage, perturb and observe maximum power point tracking algorithm connected with photovoltaic panel is performed. The main objective of this contribution based on proposing a self-correction algorithm to adjust misalignment between primary and secondary coils caused by a random parking of the electric vehicle and to produce suitable input power battery at important frequency level.
