Abstract: A converter and a method of operating a switching converter in a low power mode are presented. The invention relates to a III/V semiconductor switching converter. A switching converter contains a first power switch coupled to a second power switch via a switching node. There is an inductor coupled to the switching node, and a clamp circuit containing a third power switch is coupled in parallel to the first power switch. The switching converter is adapted to turn the first power switch off and to enable control of the third power switch upon identifying that the switching converter provides a low level of power.

Abstract: The invention relates to a method for separating water from a gaseous working medium (2), at least the following steps being carried out: providing an ionic hygroscopic liquid (4) in a reaction chamber (3); supplying the water-containing working medium (2) and conducting the working medium (2) through the ionic liquid (4), wherein water bonds with the ionic liquid (4) and is thereby separated from the working medium; and discharging the dried working medium (7). The invention further relates to a corresponding water separator (1) and to a water separator system (15).

Abstract: A compression machine (110) includes an oscillating body (111) oscillating between two reversal points (U1, U2), wherein the oscillating body has a first mass (m1), and a maximum value of resulting compression force (F*) when the oscillating body is used is less by a predetermined factor (F) than a maximum value of the resulting compression force when an oscillating reference body (121) having a reference mass (mref) is used in a reference compression machine (120) of same construction and using the same fluid (112), wherein the first mass exceeds the reference mass by a percentage that is a function of the predetermined factor, and wherein maximum value of the resulting compression force is reduced by the predetermined factor F by reducing cross-sectional area (A) of the oscillating reference body if the oscillating reference body were used. A related method is also provided.

Abstract: A piston compressor for compressing a cryogenic fluid medium, in particular in the form of hydrogen is described. It is provided according that an encircling first gap between a first piston and an inner side, facing towards the first piston, of a first cylinder is sealed off by means of at least one seal, which is provided on the first piston, in such a way that leakage medium from the first cylinder interior space passes through the first gap into the interior space of the housing and flows around the rotor and in particular also the stator, wherein the permanent magnets are provided with a coating in order to protect against the medium, in particular in order to protect against hydrogenation in the case of a medium in the form of hydrogen. A method for compressing a cryogenic fluid medium, in particular hydrogen is also disclosed.

Abstract: A collecting tank, for a potentially flammable or explosive environment, includes: a collecting chamber for fluid having a condensate inlet; and a suction opening for extracting fluid. The tank also includes: a Venturi nozzle fluidically connected to the suction opening to generate a vacuum in the suction opening; a pressure medium inlet fluidically connected upstream of the Venturi nozzle to generate a vacuum in the suction opening when pressure medium is introduced into the Venturi nozzle; and an extraction outlet fluidically connected downstream of the Venturi nozzle and to the suction opening, for extracting fluid from the collecting chamber. Methods of operation for the collecting tank and a hydrogen-powered vehicle utilizing the collecting tank are also described.
