  • Technique for disconnecting the actuation of a power stage
    Patent number: 12143045
    Abstract: A device for disconnecting an actuation of a power stage of an electric machine includes: a first input for detecting a safety function signal and a second input for detecting a reference potential of the safety function signal; and at least one switch-off path of the actuation, each of the at least one switch-off path including: an input coupler connected between the first input and the second input on an input side for transmitting the safety function signal from the first and second inputs; and at least one output for actuating a switch of a half bridge of the power stage, and at least one modulation logic unit for logically linking a modulation signal associated with a respective switch and the safety function signal transmitted by a respective input coupler and to output it at the output as a disconnectable modulation signal.
