Manufacturing and Commissioning of an Ultra-Compact Motor Inverter for Implantable Artificial Hearts

Novel total artificial hearts (TAH) or ventricular assist devices (VAD), i.e., blood pumps, can be implanted in conjunction with a transcutaneous energy transfer system (TET). This creates the need for an ultra-compact implantable motor inverter with high efficiency. A prototype inverter was designed and must now be commissioned.

Systemanalyse mit Linearmotoren

In industriellen Mehrachsensystemen können mechanische Kopplungen und begrenzte Steifigkeit zu unerwünschtem Betriebsverhalten führen. Es soll ein Systemanalyse-Tool entwickelt werden, das mithilfe der integrierten Servomotoren automatisierte Messungen durchführen sowie positionsabhängige mechanische Kopplungen und Schwingneigungen ermitteln, analysieren und visualisieren kann.

Design and Construction of a Remotely Controlled Variable Power Inductor

Accurate soft-switching measurements require a wide range of inductances to evaluate switching losses at various turn-on currents. Using a discrete set of inductances is inefficient and time-consuming, making a high-current variometer with mechanically adjustable inductance a more desirable solution especially when considering the possibility of remote adjustment via a MATLAB script.

Realization and Characterization of a Transcutaneous Energy Transfer System

Percutaneous drivelines are the major cause for infections after implanting a mechanical circulatory support system (e.g., a ventricular assist device or a total artificial heart). Inductive power transfer systems are a promising alternative. The main challenges are the heating of the tissue and the limited allowed power dissipation for implanted power electronics.
