Automotive transient immunity generators are required to meet conducted electrical disturbance immunity standards such as ISO 7637, ISO 16750-2 and others. Generating the electrical transient pulses and, typically using an internal coupler, the automotive transient generators apply waveforms defined it test standards to supply lines and assemblies used in cars and other vehicles.
The EMC Shop stocks a wide selection of automotive transient generators from Teseq, EM Test and 3ctest. Rent or buy an automotive transient generator for virtually any international or manufacturer specific test standard requiring immunity testing to electrical disturbances on cars, trucks or industrial vehicles. Software can be easily added and integrated to include additional tests as required.

Automotive transient generators are typically benchtop, but heavy equipment. When doing testing on three phase power lines systems usually require much larger coupling/decoupling networks which substantially increase system size. EM test environments with ground planes with connections to earth are required to safely use transient generators.

Test Standards Requiring Automotive Transient Generators
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 a 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. Sinusoidal noise coupled on battery lines. Often referred to as “ground shift”.
The EMC Shop stocks automotive voltage drop simulators to test components to be used in electric vehicles (as well as gas-powered). Meet ISO 7637-2 and other industry standards as well as manufacturer standards or use software to customize or replicate voltage dropouts that you want to expose your device to.
Voltage Drop Simulation test setup
Most of our customers will simply place the voltage drop simulator on a bench, ground the chassis, and be off and rolling. There are diagrams avaialble that specify spacing, placement, etc... We have found that in most cases, these aren't detrimental unless striving for full compliance.

Be sure the generator and external coupling devices are well grounded. Start testing at lower voltage levels to observe how your DUT responds as well as surrounding equipment in your test area. Your test setup may require you to move equipment and/or isolate your test area a bit more.
