摘要： The contactless transmission of electrical power has many important advantages in modern technology through the lack of electrical contacts and therefore of their ageing, the facile use in aggressive or explosive environments, in marine environments, medical applications, in electrical vehicles, in robotics. The efficiency is comparable to the galvanic contact transmission at small and medium distances but there is also the ability to simultaneously transmit energy and data. The paper makes a review of the main recent Romanian and foreign publications on the main techniques of contactless power transmission, regarding the optimization of the coupler 'figure of merit', and compensation topology, using both circuit analysis and FEM analysis. A recent application to contactless transmission via conductive fluids is discussed. Also, there are discussed the perspectives of the research, development and use of the described methods in the following years, in the scope of achieving interoperability, increasing the efficiency and the power transfer.
