Abstract: An electronic circuit arrangement for a fuel cell arrangement may include a first electrical voltage converter stage and a second electrical voltage converter stage. An electrical fuel cell voltage may be appliable to the first electrical voltage converter stage on an input side. The electrical fuel cell voltage may be convertible into a first electrical output voltage of the first electrical voltage converter stage via the first electrical voltage converter stage. The first electrical output voltage may be appliable to the second electrical voltage converter stage on an input side. The first electrical output voltage may be convertible into a second electrical output voltage of the second electrical voltage converter stage via the second electrical voltage converter stage. An electrical interconnection of the first electrical voltage converter stage and the second electrical voltage converter stage may be switchable between a first interconnection state and a second interconnection state.

Abstract: A turbine arrangement for a turbine may include a turbine wheel and a magnetic coupling having a first rotor and a second rotor, each of which may be rotationally movable about a common axis of rotation defining an axial direction. The first rotor maybe connected to the turbine wheel in a rotationally fixed manner, and may be magnetically coupled with the second rotor in the axial direction. At least one of the first rotor and the second rotor may include a base part, at least one magnetic element, and a holder on an end face of the base part facing the other rotor and in which the magnetic element may be retained. The holder may be designed as a retaining collar projecting axially from the second base part to the other rotor, and into which the magnetic element may be inserted.

Abstract: A spiral compressor may include a stationary first spiral member and an orbiting second spiral member intermeshing with the first spiral member. The spiral compressor may include a pendulum slide mechanism that may have an inner ring and a stationary outer ring connected to the inner ring via a plurality of pendulums. The pendulum slide mechanism may include an eccentric member disposed on a radial inside of the inner ring with respect to a central access of the inner ring. The inner ring on an inner circumferential side may be drivingly connected to the eccentric member and on an outer circumferential side may be rigidly connected to the second spiral member. The second spiral member may transmit an orbiting motion in relation to the first spiral member via the pendulum slide mechanism when the eccentric member is driven.
