Abstract

Wireless Power Transfer (WPT) is the transmission of power from the source to load without any power cord. WPT technology is used for wireless charging for consumer electronics like mobile, laptop and electric vehicles. This review outlines a systematic investigation of WPT technology covering the fundamental principle of Resonance Inductive Power Transfer (RIPT) and various types of WPT. Underwater Wireless Power Transfer (UWPT) is just an emerging technology which is used to power the unmanned underwater vehicle applications. A comprehensive review of various methods in WPT is done. The study also reviews multiple receiver WPT system, power transfer efficiency and wireless power charging of portable device, Medical Implant Micro systems (MIMs), electric vehicle and military applications.


Description

Wireless Power Transfer (WPT) is an emerging technology, which offers power transfer from source to load without any wires. Recently, WPT is used for many applications like charging portable electronic devices, medical implant micro system (MIM) devices with rechargeable batteries and high power Electric Vehicle (EV) (Wu et al., 2011). WPT increases the mobility and reliability of the system at low cost. This technology gives freedom from annoying wires. The core process of WPT is Electromagnetic (EM) energy which is transmitted from power source to load in air medium. The idea of transmitting power through air is introduced by Tesla (1914) and used by Grover and Sahai (2010). Later in the early 21st century, the non-radiative WPT system based on EM coupling gained much more popularity when the use of portable consumer devices became widespread. WPT can be considered to be radiative and non-radiative based on the energy transfer mechanism (Baarman and Innovation, 2014). Radiative power can be emitted from an antenna and propagate through any large medium in the form of EM wave. On the other hand, the non-radiative WPT technology is typically based on the principles of Nikola Tesla using near-field inductive coupling and magnetic resonant inductive coupling, applicable for short and mid-range energy transfer applications, respectively (Hui et al., 2014; and Barman et al., 2015).
