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.
