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).
