Wireless Power Transfer for Electric Vehicles Application using the Principle of ICPT System

Abstract

Wireless Power Transfer is method of transferring the power from the power source to the electrical load without the physical contact, by using the principle of magnetic resonance. Due to the increase in the cost of the petroleum product and environmental issues led to development of the Electrical Vehicles (EV’s) globally for transportation. The charging of electric vehicles using wire causes losses therefore, it decrease in efficiency of the system. The preliminary review of the WPT analysis tells that the Inductively Coupled Power Transfer system ICPT is one of the promising and convenient methods for charging the EV’s. The paper is about designing the circuit using the MATLAB Simulink Software .The results for different values of load versus Efficiency of the system of ideal case is been plotted were the maximum efficiency is around 98% assuming the alignment errors as zero. The system parameters and performance equations are coded using MATLAB for Model based design for charging the EV application. Also, efficiency and load curve characteristics are demonstrated. The paper demonstrates the experimental setup of the same for the distance of about 15 cm. Each part of the setup and the components used along with their features has been discussed briefly. The same setup for higher power rating can be implemented in future with design modifications.
