A sensitivity study on an inductive contactless power transfer system

The paper focuses on the sensitivity analysis made on an inductively coupled contactless power transfer system. The study uses the symbolically form of the circuit functions. After that the circuit function was obtained, it was introduced in a Matlab program for processing and utilization in the sensitivities formulas. The sensitivity characteristics were obtained for each circuit parameter, the most representative ones being presented in the paper. Both dependencies on frequency and on parameter variation were considered. Finally some conclusions were established regarding a certain case study.
