Evaluation of radiated emission from transcutaneous energy transmission system for a totally implantable artificial heart

Abstract

This paper reports on evaluation of radiated emission from transcutaneous energy transmission system for a totally implantable artificial heart. The radiated emission from the coreless type (transformer A) and the externally-coupled type (transformer B) of the transcutaneous transformers are measured, respectively, and compared with German regulation of VDE-0871 for medical electric equipment. From the measurement, the radiated electric field intensities at 100kHz from the transformers A and B are 67.7dBμV/m and 38.7dBμV/m, respectively. As a result, it is found that the radiated emission from the transformer B is sufficiently small compared with the level regulated in VDE-0871.
