Optimization Model of the Transcutaneous Energy Transmission System for Achieving Maximum Power Transfer Capability

Transcutaneous energy transmission (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. Proper performance of the TET system requires optimization of their electronic component parameters. In this paper, an optimization model is proposed for the preliminary design for two compensated capacitance and two coil inductance. The objective is the power transfer capability of the system. The design variables include the primary and secondary coil inductance. The constrained conditions are peak over-voltage, peak withstand current of the system electronic components and bifurcation phenomenon. This model provides a new and useful tool for determining the compensated capacitance and coil inductance of the TET system. The theoretical analysis is verified by simulated and experimental results. The maximum power transfer capability can be achieved through the optimization solutions in steady-state.
