TECHNIQUES FOR ACTIVATING CONTROL OF POWER STAGE

The invention relates to a device (100) for activating a control of a power stage (200) of an electric machine (300). The device comprises a first input (102) for detecting a safety function signal and a second input (104) for detecting a reference potential of the safety function signal. In additio...

More Information
Summary:The invention relates to a device (100) for activating a control of a power stage (200) of an electric machine (300). The device comprises a first input (102) for detecting a safety function signal and a second input (104) for detecting a reference potential of the safety function signal. In addition, the device comprises at least one turn-off path (106) of the control. Each switching-off path (106) comprises: an input coupler (110), which is connected on the input side between the first input (102) and the second input (104) and is designed to transmit the safety function signal from the inputs (102, 104); at least one output (130) for controlling a switch of a half-bridge of the power stage (200); and at least one modulation logic unit (120) designed to modulate a modulation signal (166; 168) and the safety function signal transmitted by the associated input coupler (110) are logically associated and output at the output (130) as an activatable modulation signal (108). The input coupler (110) transmits the
