Optimal Design of the TET System for Achieving Maximum Power Transfer

Transcutaneous energy transfer (TET) systems have been a topic of intense research. Such systems play an important role in offering the opportunity to provide power to implantable biomedical devices through wireless power transmission. It eliminates the serious infection risk associated with direct cable connections through the skin. Research to optimize power transfer capability to a biomedical implantable device has never been more intense. In this paper we present an optimization method to improve power transfer capability. A significant advantage of this method is that it uses a nonlinear inequality constrained optimization algorithm to calculate the inductance values of the primary and secondary circuits. This enables the optimization of the power transfer capability of the TET system which can now transfer enough power to biomedical implantable devices for a wide range of patient needs. All of the results were verified by simulation using MATLAB.
