Abstract: Various embodiments of the teachings herein include a power converter. The power converter may include: a converter for converting between a first electrical voltage and a second electrical voltage; a common mode filter having a common mode transformer; and a second winding connected to a frequency-selective passive damping circuit arranged on a common core. The common mode transformer has at least two first windings arranged in the same direction on the common core and coupled in series into electrical conductors connected to the converter device.

Abstract: The present disclosure relates to a method and an apparatus for the contactless measurement of the steering angle of an aircraft landing gear, in particular of a nose landing gear. Furthermore, this present disclosure relates to an aircraft landing gear, in particular a nose landing gear, which allows a contactless measurement of the steering angle.

Abstract: A modular high-frequency converter includes submodules, each having an input-side half bridge and a DC link circuit with a DC link capacitance connected in parallel to the half bridge. A DC link circuit voltage drop across the DC link capacitance of each submodule is controlled to a target voltage by adjusting a duty cycle with a closed-loop control structure having a pilot control and a downstream closed-loop error control. Within the framework of the pilot control, a target value for each duty cycle and a target value for the supply current are determined, using a mathematical model of the converter, based on the load-side output currents flowing out of the DC link voltage circuits and on target values of the DC link circuit voltages. Switch position parameters, which map the effect of the switch positions of the input-side half bridges, are each replaced by an associated duty cycle.

Abstract: The invention pertains to a weapon that provides a range control (2), by means of which it is possible to set firing velocity, and thus impact velocity, of the ammunition or active bodies (10) to a distance to be discharged in such a way that, in particular, the non-lethal ammunition (10) continues to have a non-lethal effect. To this end, a type of pneumatic weapon (1) is described that, with the use of a shot pressure control, e.g. by means of a proportional pressure regulator (3), and/or additionally in combination with breech technology and valve technology, has a continuously variable range control.
