The use of coreless transformers is still limited because of the power they can transmit and the reactive power they absorb. This paper introduces a comprehensive theoretical approach of the transferable power and the related compensation topologies allowing to optimize the system used. Analytical equations are given in order to estimate the maximum power transmission of a coreless transformer. Based on the theoretical results the optimal topology can then be selected accordingly to the power source, the transformer and the sensibility over the deviations of the elements. This methodology has been validated experimentally and allowed to transmit 2W through a 2.25 cm2 coreless transformer under 1 MHz. Moreover this results can be broaden to any inductive power transfer system.
