<p> A transcutaneous energy transmission system (TETS) is one means of supplying power to a ventricular assist device. In the system developed in this study, to prevent necrosis, we set the distance between the transmitting and receiving coils to 2 cm, assuming that the receiving coil is embedded between the subcutaneous and muscle tissues. However, as the distance between the coils increases, the input impedance decreases because the electromagnetic coupling between the coils is reduced. Hence, a stable power supply cannot be provided, and coil heat is generated. To overcome this problem, in the proposed system, the power transmission is stabilized by a newly designed impedance converter, and coil heat is suppressed by changing the number of layers of the transmitting coil. As the result, a stable power supply can be provided, and a maximum transmission efficiency of 72.7 % is achieved. Furthermore, coil heat is reduced by 15.1 °C.</p>
