An energy transmission system for an artificial heart using leakage inductance compensation of transcutaneous transformer
A power supply system using a transcutaneous transformer to power an artificial heart through intact skin has been designed and built. In order to realize both high voltage gain and minimum circulating current, compensation of leakage inductances on both sides of a transcutaneous transformer is proposed. A frequency region which realizes the robustness against coupling coefficient and load variation is identified. In this region, the converter has inherent advantages such as zero voltage switching (ZVS) or zero current switching (ZCS) of the switches, high voltage gain, minimum circulating current, and high efficiency.
