ISO 7637-2 Automotive EMC Test Equipment

Pulse 1.

A simulation of transients due to supply disconnection from inductive loads; it applies to a DUT if as used in the vehicle, it remains connected directly in parallel with an inductive load.


Pulse 2a.

Simulates transients due to sudden interruption of currents in a device connected in parallel with the DUT due to the inductances of the wiring harness.


Pulse 2b.

Simulates transients from DC motors acting as generators after the ignition is switched off.


Pulse 3a/3b.

Occurs as the result of switching processes. The characteristics of this pulse are influenced by distributed capacitance and inductance of the wiring harness.

Pulse 4.

The voltage reduction caused by energizing the starter motor circuits of the internal combustion engines.


Pulse 4 variants.

Most manufacturer variations of pulse four are generally much more complicated. For example Ford requires up to four arbitrary generators with four outputs to be perfectly synchronized.


Pulse 5.

Simulation of a load dump transient occurring in the event of a discharged battery being disconnected while the alternator is generating charging current with other loads remaining on the alternator circuit at this moment.


Magnetic field immunity.

Simulates magnetic fields generated by electric motors, daytime running lamps, etc. for DUTs with magnetically sensitive devices.


Transformer coupled sine waves.

Sinusodial noise coupled on battery lines. Often referred to as ground shift.

    ISO 7637-2 Test pulses 5a and 5b

    Load Dump Test Automotive Waveform per ISO 7637This test is a simulation of load dump transient, occurring in the event of a discharged battery being disconnected while the alternator is generating charging current and with other loads remaining on the alternator circuit at this moment; the load dump amplitude depends on the alternator speed and on the level of the alternator field excitation at the moment the battery is disconnected.

     

    The pulse shape and parameters for an alternator with no centralized load dump suppression (pulse 5a).

     

    The pulse shape and parameters for an alternator with centralized load dump suppression (pulse 5b).
