A study of the asymmetry effect of the coils for the transcutaneous energy transmission system

Abstract

The skin through cable is used for the energy transmission of artificial heart and is one of the major source of infection. To solve this problem, the transcutaneous energy transfer system (TETS) was developed. TETS are conducted energy transmission by using magnetic coupling between inside coil and outside coil of the body, improving the transmission efficiency is expected by using the magnetic resonance. The same coil for both transmission-side power receiving side is used in the energy transmission using the magnetic resonance. On the other hand, a large outside coil and small inside coil were used for the TETS in order to easily obtain a high transmission efficiency. So the effect of the difference of the coil characteristics of the power transmission side receiving side of TETS is given to the transmission efficiency of the magnetic resonance and energy, were investigated by simulation transmission circuit.
