Design of a Wireless Power Transfer for Contactless Charging System Using Bio-Inspired Algorithm

A wireless power transfer (WPT) platform optimization design for a contact less charging system is proposed. Drawbacks of WPT include low power transfer, low operation efficiency, and unstable output voltage, which are caused by various air gaps between the coils. A shuffled frog-leaping algorithm (SFLA) is hence applied to obtain the optimal frequency, meanwhile anticipating reaching the maximum output power and highest efficiency. Through the assistance of this bio-inspired algorithm, circuit simulations indicate that noises interfere can be restricted along with a maximum transfer power of 27 W and a conversion efficiency of 81%. This test outcome helps confirm the feasibility of bio-inspired algorithm for wireless power transfer design and its applications.
