摘要：
External power source, system for controlling and method for predicting heat loss of implantable medical device during inductive recharging by an external primary coil. A primary coil inductively couples energy to a secondary coil when energized and placed in proximity of the secondary coil. Control circuitry, operatively coupled to said primary coil, determines the energy absorbed in said tissue based on a total applied power by said external power source, power lost in said electronic circuitry, power lost in said electronic circuitry, power lost in said primary coil and power applied to said rechargeable power source and controlling said total applied power based upon said energy absorbed in said tissue.
