The Transcutaneous Energy Transmission Systems (TETS) can non-invasively transmit power to a totally-implantable artificial heart. One of the most important problem is the improvement of power transfer efficiency. We aimed to improve the power transfer efficiency by applying a class-E amplifier and reducing the switching loss. Moreover, the insertion mode of the capacitor for resonance (series resonance or parallel resonance) and the rectification mode are also important. We compared the power transfer efficiency and the frequency characteristics by the resonance circuit and the rectification mode by simulation.
