Design and Simulink Implementation of Electrical Vehicle Charging Using Wireless Power Transfer Technology

In present era, wireless power transfer system is gaining popularity owing to its application in wide areas like wireless charging of devices such as cell phones, laptops, electric vehicles, underwater vehicles and implants. Inductive power transfer (IPT) is a type of wireless power transfer technology. It is emerging as a modern power distribution system even in harsh environment. This paper focuses on designing a IPT-based wireless power transfer charger for electric vehicle. For this, series–series (SS) compensated IPT system is designed. First, the designing formulas are derived for SS compensated IPT system. The designing procedure takes care of bifurcation phenomenon which is one of a vital issue in implementation of an efficient IPT system. Based on the designing formulas derived, electrical parameters are calculated for designing a 7.7 KW wireless power charger meeting SAEJ2954 standards which have not been met in previously published work. Finally, the proposed IPT system is implemented on Simulink platform.
