Time-domain Analysis and Simulation of Wireless Power Transfer in Motion

The most widespread use of wireless power transfer (WPT) technology is for use between two stationary objects. Generally, one object is the power source, and the second is the object to be charged; in this study, they are referred to respectively as the primary and secondary sides. This study focuses on modifying and applying existing equations for use in time-domain analysis to discern the behavior of WPT systems with an in-motion secondary side. The methods within this study approximate the complex WPT system and can be obtained faster and with fewer resources than the current industry standard of finite element method analysis.

I. Introduction

The world is continuously evolving. Technology continues to push the boundaries of what is possible. The speed and reach of the dissemination of information and the availability of technology have continued to increase. Countries continue to become increasingly developed, and new countries achieve the criteria to be considered a developed country. With all of this increase in development and technology comes the need for power and mobility. Battery technology has come a long way from the initial invention, and now devices like our phones can have batteries that last one or more days. Portable battery banks are becoming everyday household items and have large capacities that can charge devices while you are away from power plugs.
