High-Efficiency Converter for Transcutaneous Power Transfer

As part of the Zürich Heart project at ETH, I designed and built a high-efficiency converter for transcutaneous power transfer. This converter design would be implanted inside a human body and used to help operate a blood pump using wireless power transfer. The design achieved 98.7% peak efficiency.

Using state-of-the-art GaN (Gallium Nitride) transistors in a novel configuration, with closed-loop control using an FPGA and a DSP.
