Abstract
To get the higher efficiency, source voltage must be chosen as high as possible unless the magnetic flux density passes through the core exceeds the saturation flux density. Using pot core of 36mm diameter, 67% and 78% of maximum system efficiency was measured when 24w were transmitted at 50kHz.In vitro enough power to drive the motor driven artificial heart was transmitted. Pump outflow of 4.0L/min. was obtained under the condition of supply voltage of 14V, drive rate of 94bpm, preload of 15mmHg, afterload of 90mmHg. The secondary part of transmission system includes the subsidiary battery which is charged in trickle method and the primary part includes some alarm functions. Feasibility of the systems were verified.
