“…Em [40], por meio de um procedimento experimental comprova-se a equivalência de ambas as formulações: para diferentes distâncias entre emissor e receptor, a eficiência de transmissão obtida pela formulação proposta na Introdução deste trabalho apresenta erro inferior a 4% em relação ao que se obtém pela formulação de [37]. Desta forma, os conceitos usuais de circuitos elétricos são suficientes para qualquer análise em transferência indutiva de potência, não obstante a distância entre emissor e receptor ou a frequência f 0 .…”

Resumo -O objetivo deste trabalho é apontar as atuais fronteiras do conhecimento em Transferência Indutiva de Potência. Para isso, é feita a divisão por tópicos, que abordam de forma compreensível os diversos assuntos relacionados à transferência de potência elétrica sem contatos sólidos entre fonte e carga, a partir de extensa revisão da literatura da última década. São apresentados e comentados os resultados de pesquisas relevantes quanto à formulação matemática dos princípios desta tecnologia e os procedimentos de projeto de conversores especiais. Evidenciam-se ainda os estágios de processamento de energia, para todas as faixas de frequência e potência para as quais atualmente existem resultados experimentais, e respectivas técnicas de controle. Patentes referentes a aplicações comerciais são mencionadas ao longo do trabalho. Uma discussão sobre limites de exposição aos campos eletromagnéticos e certificação das soluções completa o trabalho.

SELECTED TOPICS ON THE STATE-OF-THE-ART OF INDUCTIVE POWER TRANSFER Abstract -The objective of this paper is to point the current frontiers of knowledge in Inductive PowerTransfer. This is done by dividing the theme in threads to deal comprehensibly with the various issues related to the transfer of electrical power without solid contacts between source and load, based on an extensive literature review of the last decade. Results of relevant research on the mathematical formulation of the principles of this technology and design procedures for special converters are presented.

“…Many authors have termed this technology as the inductively coupled power transfer (ICPT), while Kurs et al [32], and Karalis et al [33] termed this method as the strong magnetic coupled power transfer. Nevertheless, both of these indicate same characteristics [13,34]. Takanashi et al [35] split IPT based on the use of the magnetic core and operating frequency into the inductively coupled power transfer (ICPT ) method [31] and the magnetic resonant power transfer method [32,33].…”

a b s t r a c tThe deficiency in the availability of petroleum products has given rise to the incorporation of electric vehicles (EVs) globally as a substitute for the conventional transportation system. Significant research has been pursued over last two decades in the development of efficient EV charging methods. A preliminary review of few methods developed for wireless charging revealed that ICPT is a promising and convenient method for the wireless charging of EVs. This paper includes the equivalent circuit analysis and characteristics of the ICPT system and focuses on the research progress in respect of the designs for the charging coil, leakage inductance compensation topologies, power level enhancement and misalignment toleration. The improvement in these factors has been essential for the implementation of EV charging. A brief discussion over design process and control of ICPT system has been added. Conclusions have been made on the basis of the information extracted from the literature and some future recommendations are provided.

“…As another kind of wireless power transfer techniques, inductive power transfer (IPT) has developed for more than twenty years [5], and it mainly focuses on the high power level applications, where the issues of concern normally include power conversion and control [18,19], magnetic structure design [20], control algorithm and strategy [21,22] as well as circuit topology [23]. Basically, both SCMR and IPT conforms to Faraday's and Ampere's laws, and their differences primarily include the design approaches, system architectures, parameter selection and transfer characteristics [6,24].…”

Design and Control of a 3 kW Wireless Power Transfer System for Electric Vehicles

This paper aims to study a 3 kW wireless power transfer system for electric vehicles. First, the LCL-LCL topology and LC-LC series topology are analyzed, and their transfer efficiencies under the same transfer power are compared. The LC-LC series topology is validated to be more efficient than the LCL-LCL topology and thus is more suitable for the system design. Then a novel q-Zsource-based online power regulation method which employs a unique impedance network (two pairs of inductors and capacitors) to couple the cascaded H Bridge to the power source is proposed. By controlling the shoot-through state of the H Bridge, the charging current can be adjusted, and hence, transfer power. Finally, a prototype is implemented, which can transfer 3 kW wirelessly with 95% efficiency over a 20 cm transfer distance.
