Grounding Scheme for AutoBox/Tandem AutoBox
Provides notes on connecting ground.
Influences on Board Performance Using
AutoBox/Tandem-AutoBox
To handle the voltages and currents from a car battery, the boxes are
supplied with a special power supply. If noise seems to be a problem for
your dSPACE boards installed in the AutoBox/Tandem-AutoBox, you
should consider the information in this chapter.
Filter Circuit for AutoBox/Tandem-AutoBox Power
Supply
In special cases (mainly, if cabling and grounding is not performed
properly) the AutoBox power supply can cause conducted interferences
to other electronics installed in the car. However, only electronics that are
sensitive to conductive interferences (like measuring amplifiers) are
affected.
A filter circuit at the AutoBox power input can reduce these interferences.
Grounding Scheme for AutoBox/Tandem AutoBox
The AutoBox/Tandem
‑
AutoBox should be made the center of the
ground star.
The power supply should be routed by two twisted or parallel, large
diameter wires from car battery to the AutoBox power input
connector.
