Abstract:
1. A circuit arrangement for aircraft engine controllers for providing or generating a bipolar direct current output signal as a function of at least one pulse-width modulated input signal, comprising: a first driver stage and a second driver stage, the first and the second driver stages being activatable by a pulse-width modulated input signal, and at least one of the first and second driver stages being connected to a step-down converter stage so that, when the first driver stage is activated, a first switching element of the step-down converter stage activates a low-pass device of the step-down converter stage, and, when the second driver stage is activated, a second switching element of the step-down converter stage activates the low-pass device of the step-down converter stage.
