A Review of Inductive Power Transfer: Emphasis on Performance Parameters, Compensation Topologies and Coil Design Aspects

Abstract

Wireless Power Transfer (WPT) using inductive and magnetic resonance coupling developing at enormous pace due to its diversity of applications, such as electric vehicles (EV), biomedical implants, consumer electronics, robotics and so on. This review presents historical background together with applications of low power and high power WPT systems. The review emphasizes on two main design facets of WPT system including compensation networks and coil structure. All up-to-date compensation topologies are comprised in the review along with latest coil designs. Load-independent operation using compensation topologies is also reviewed. The review provides all available methods to analyze the circuit structure of WPT system theoretically and it also outlines the software used for circuit simulations as well as coil design. This paper is diverse from existing reviews in a pattern that it presents not only complete critical intuition on the vital design features, recent advancements, contemporary problems and challenges of low power and high power WPT systems but also provides the available theoretical methods as well as software to analyze the WPT system in wholesome. This paper will enrich the knowledge of the researchers to investigate the WPT systems using existing techniques and to solve the present-day design glitches of WPT systems
