| Sumario: | A wireless transcutaneous energy transfer (TET) system is researched. The characteristic functions of system voltage gain and transmission efficiency are obtained by circuit analysis. Meanwhile, according to the typical technical parameters of the TET system, a characteristic analysis is conducted. Therefore, based on the energy injection technique, a variable frequency constant voltage control method is proposed which enables the TET system to operate at a high efficiency all time when both the load and the transfer distance change. The experimental set of the TET system is arranged. The experimental results have verified the correctness of the theoretical analysis and design scheme. When the transfer distance is fixed, the overall efficiency remains constant in the whole load variation range. The overall efficiency of the TET system is above 83% within typical transfer distances. The multi-physics simulation software is used to simulate the human tissue safety. The simulation results show that the maximum electric field strength, the specific absorption rate, and the maximum temperature are lower than their corresponding limitations. |
