Compensation and Emulation of Output Impedance in Ultra-High Bandwidth Class-D Power Amplifiers
(2021)2021 IEEE 22nd Workshop on Control and Modelling of Power Electronics (COMPEL)The stability limits for an ultra-high bandwidth class-D power amplifier (100kHz, 800V DC-link, 10kW) are derived and characterized for two different use cases and for a given inductance of the line that connects the output of the converter to the load. In the first use case, the additional impedance due to the line is compensated and in the second use case, a controlled inner ohmic-inductive impedance is emulated by the converter.

Optimierung sicherheitskritischer IFR HelikopterTrajektorien in Alpinem Gelände mit MILP
(2021)AHORN 2021 - ProceedingsFlüge unter Instrument Meteorological Conditions (IMC) in alpinem Gelände werden in grossen Höhen durchgeführt, um das Terrain-Kollisionsrisiko sehr klein zu halten. Bei Helikopterflügen ergeben sich dadurch zwei gewichtige Nachteile. Nicht annehmbar ist dabei die mit zunehmender Flughöhe ansteigende Vereisungsgefahr der Rotorblätter, zudem verlängert sich die Flugzeit durch die längeren Steig- und Sinkphasen. In diesem Vortrag wird ein ...Other Conference Item -
