Analysis and Modelling of Basic Wireless Power Transfer Compensation Topology: A Review

Abstract

AbstractWireless power transfer (WTP) emerged back in the early 1890s. This electrical technology captured major attention when a group of MIT researchers designed a functioning model of a WPT system that was efficiently able to transmit power and light a bulb of 60 W at a distance of 2 m. However, this concept was first put up by a Serbian scientist, Nikola Tesla, who introduced a system that could auspiciously transfer electrical power wirelessly. In this chapter, a detailed discussion on WPT and relevant methodologies and operation techniques is presented. A wireless power transfer system employs three distinct technologies: inductive, capacitive, and radiant. In this article, four fundamental compensation topologies of resonant WPTs are described, which are series–series (SS), parallel–parallel (PP), series–parallel (SP) and parallel–series (PS). Standard parameters and equation modelling have been discussed in this chapter. The world needs a wire-free system, and that is the hope of every other Tesla-influenced researcher. Every knowledge provided in the chapter is purely true to its deepest extent. The production and development of battery-powered devices face unparalleled technological difficulties because of the drawbacks of poor power density, exorbitant prices and bulky structure, etc. The wireless power transfer introduces a new energy acquisition method for electric vehicles as a novel energy pattern. This chapter also summarizes WPT approaches focusing on operating structures, mathematical and technological challenges focusing on the system for WPT.KeywordsWireless power transferTeslaTopologiesElectric vehiclesPlug-in charging
