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. Moreover, considering experimental results, this work discusses power stages for different frequencies and power levels and their control techniques. Patents related to novel techniques in commercial appliances are cited along the work. A discussion on limits for electromagnetic fields exposure and certification of solutions completes this work.

Abstract The aim of this work is to show a preliminary investigation of possible non-contact techniques for displacement measurement of radioactive waste in a geological disposal. Since a nuclear waste repository can be considered as a harsh environment, the possibility to study alternative methods for measurement, for example not using cables or buses for detecting relevant data, should be considered as a priority. A straightforward approach could be the substitution of cables with wireless sensors. But if cables cannot be used and the use of wireless techniques is required, new sensors must assure a reliable transmission without affecting the engineered barriers performance and the reliable use of energy supply for the measuring equipment over long periods. This work shows the results of a study of feasibility on using an electromagnetic approach for the contactless displacement measurement of a canister immersed and suspended in bentonite, a material with a high degree of water retention.
