Cardiac pacemaker has to be changed in three to five years for the battery life. A patients must be performed an operation whenever a patient is changed cardiac pacemaker. The method employing secondary rechargeable battery is researched to extend the battery life. The secondary rechargeable battery is transcutaneously charged from outside the body. This paper presents a transcutaneous energy transmission system for a rechargeable cardiac pacemaker battery. The transcutaneous energy transmission system is constructed with a high frequency resonant inverter, a transcutaneous transformer and a rectifier circuit. The secondary transformer is piled and the coupling coefficient and the conversion efficiency are measured with an experimental set up. The results show as follows. The best diameter of the primary center core is 15[mm]. The best output voltage frequency is 10[kHz].
