Abstract: A voltage supply device for an aircraft control device having a first and a second main channel arrangement for redundancy and reliability, wherein the voltage supply device has a first and a second output transformer, wherein a first output inductor of the first main channel arrangement is designed as a primary winding of the first output transformer, and the second output inductor of the second main channel arrangement is designed as a primary winding of the second output transformer; and wherein the voltage supply device has at least a first secondary channel arrangement, wherein the first secondary channel arrangement has a first secondary voltage output and a first secondary winding of the first output transformer and a first secondary winding of the second output transformer, wherein the first secondary voltage output is connected to the first secondary windings which are connected in parallel.

Abstract: Voltage supplies for supplying control devices for an aircraft are frequently designed to be redundant, so that the failure of individual operative parts of the voltage supply does not result in a complete failure of the voltage supply and thus the control device. The object of the invention is to provide a voltage supply device functioning in an operationally reliable manner in particular for an aircraft control device, having a manageable number of components.

Abstract: A circuit arrangement of a sensor-triggered control system in a safety critical application with a digital signal processor (DSP) is provided. The DSP calculates a first position or attitude from position or attitude signals generated by a sensor. The first position or attitude meets a predetermined requirement to be accurate and unambiguous. A signal conditioning circuit reduces information content of the position or attitude signals to generate reduced position or attitude signals. A position and attitude calculation circuit determiners a second position or attitude based on the reduced position or attitude signals, which does not meet the predetermined requirement. A control unit compares the first position or attitude with the respective second position or attitude to generate a difference and determines whether the difference is within a predetermined scope of accuracy. If the determination of the control unit is negative, a sensor fault signal is outputted.

Abstract: The invention relates to a circuit arrangement of a sensor-triggered control and/or display system in the context of a safety-critical application with a DSP and a method for monitoring the DSP, characterized-in-that the position and/or attitude signals transferred to the DSP are reduced in terms of their information content, the reduced information content is delivered to a position and attitude computation instance and checked as to whether the unambiguous position and/or attitude determined by the DSP agrees with the inaccurate and/or ambiguous position and/or attitude determined by the position and attitude computation circuit within the scope of the accuracy and/or ambiguity, and a sensor fault signal is output if the check is negative.
