What is new in ISO 7637-2:2011? Do I need to do these tests? Emissions (measuring problems) Immunity (simulating problems) What do the standards simulate? What are all these test levels and performance criteria? What are the key questions to ask myself to ensure I have the right solution? What is EMC? EMC Immunity and Emissions EMC - Electromagnetic Compatibility Three Elements of an EMC Problem The ability of a device or system to function without error in its intended electromagnetic environment. All electronic devices make noise and must be immune to noise created by other devices Measuring the noise from a device is called “Emissions Testing” Simulations of these events called “Immunity Testing” which means that the devices under test are immune to the noise Coupling Path Noise Source Affected Component What is EMC? Special Considerations for Motor Vehicles In ISO 7637 and variants, we are considering transients and voltage drops that are coupled over battery lines and signal lines Immunity Testing simulates ‘Conducted EMC’ that occurs during normal or error conditions in a motor vehicle. Emissions testing ensures that the noise created by a device is less than specified levels. Evaluates the performance of components during simulated real-world EMC events These failure conditions are documented and tests defined by International organizations (ISO, SAE) and manufacturers (Ford, VW) Causes: Alternators, Converters, Switching Processes Electric Motors, Fuel Pump, Fan Motors Lights, Radio Every kind of electronic device Coupled on Power Lines and Wiring Harnesses Engine Start Do I Need To Perform These Tests? Typical Applications Do I Need To Perform These Tests? Ford Definition Do I Need To Perform These Tests? Users: Automotive manufacturers Test Providers (Test Houses) Supplier of components or engineering services Research Laboratories What must be tested: All electronic components or subsystems prior to full vehicle testing When must devices be tested: During initial design phases During redesigns or modifications Before production and sampling during production (*) Do I Need To Perform These Tests? UN ECE R10 Rev.04 E1 Do I Need To Perform These Tests? UN ECE R10 Rev.04 Do I Need To Perform These Tests? UN ECE R10 Rev.04 Emission Standard Introduction ISO 7637-2 (2011) Emissions Electronic Switch Simulates Fast Switching ‘Artificial Network’ Simulates Vehicle Wiring Harness Battery Source Oscilloscope DUT The application is simple: The DUT is switched off, switched on, or different operation modes are exercised and any feedback is measured. In simplest terms, we’re measuring the DUT’s inductive kickback. Emissions Switch – Before or After AN? Application Wiring Harness For applications where the DUT is far from the switch, the setup should have the AN between the switch (simulating the wiring harness) and the DUT. “Slow Pulse Setup” Oscilloscope Switch Test Setup Battery Source Artificial Network Simulates Wiring Harness Impedance DUT Emissions Switch – Before or After AN? For applications where the DUT is near the switch, the setup should have the AN before the switch Application Wiring Harness “Fast Pulse Setup” Oscilloscope Artificial Network Simulates Wiring Harness Impedance Test Setup Battery Source Switch DUT ISO7637-2 Emissions Test Layout AN DUT “Slow Pulse” Setup AN DUT “Fast Pulse” Setup Emissions Relay or Electronic Switch? When to use a relay and when the electronic switch: Relay Voltages over 400V Usually must be approved by OEM Poor Repeatability, Slow/Chattering Must be replaced Should be production relay from the vehicle containing the DUT Electronic Switch Less than 400V Fast and Repeatable Voltage Drop Must be Accounted For ∆U ≤ 1V at 25 A Differences: AN(LISN) defined in ISO7637-2 & CISPR25 ISO 7637 and CISPR Artificial Network are NOT the same = 50 Ω Differences Between ISO 7637 and CISPR Artificial Networks Documenting the DUT Behavior Items to be Documented: Peak Amplitude Pulse Duration Rise and Fall Times Burst Duration (if Repetitive) Repetition and Cycle Times Other Standards Almost every manufacturer standard adheres to ISO 7637-2 for emissions measurements. They vary only slightly in setup (switch position and cable lengths). For this reason, the AES 5501 was designed in several parts so that control over the position of the switches and cable lengths is easy. One notable difference is Nissan and Renault with two LISNs: Typical DUT Behavior and Measurements Very Heavily Inductive ~ -450 V Mixed R/L Load ~ -20 V Much more severe pulses from DUTs with high inductance AES 5501 - Emissions Overview and Advantages 100 A Operation Complete System ! !

ISO 7637-2:2011 ISO 16750-2 And other common pulses 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.

The requirements are different in: Amplitude Impulse Frequency Pulse energy Test method, test setup Where do these differences come from? Wiring harness Components Generator etc. The experience of the standard writer, theoretical evaluations, empirical measurement values and different test conditions do have a strong impact on the parameterization of the pulses!

These include: ISO 7637-2:2004 Pulse 4 -> ISO 16750-2 “Starting Profile” ISO 7637-2:2004 Pulse 5a and 5b -> ISO 16750-2 “Load Dump A and B” This is logical because these are not traditional EMC events, but instead an issue of power quality. Curiously, Pulse 2b will likely remain in ISO 7637 even though it could also be classified as a power quality problem in the opinion of many experts. Other Variations Immunity Variations - Overview Dozens of manufacturer standards exist, and they differ from the international standards: Not all OEM standards are the same, even for pulse 1, 2, 3, 5 - type transients Dozens of variations in starting pulses Several new methods of generating even common pulses Flexible equipment is preferred for forwards/backwards requirements Other Common Tests Dips and drops (two variations) Coupling on signal lines (two variations) “Pulse 7” in a new form Power magnetics, transformer coupled sine waves Variations Examples Ford EMC CS 2009 Completely rewritten sections including inductive transient fixture Frequency of many tests increased to 100 kHz Overview of all new and changed tests available from Teseq Ford ES-XW7T-1A278-AC (2003) Contains Special 4Ω ISO – type pulses No verification other than defined in ISO 7637-2 Ford ES-XW7T-1A278-AB (1999) Contains 4 Ω ISO – type pulses Contains special Ford verification procedure Latest version always available at www.fordemc.com Variations – Load Dump Examples Actual test parameters vary greatly. Therefore, the test generator must be able to fulfill all of these ranges listed in the standard. Exact test parameters are based on the expected vehicle/alternator combination, and must be selected at the advice of a responsible engineer or liaison to the customer/manufacturer. Variations – Load Dump Examples Numerous manufacturers’ standards disregard the ISO wording for transient pulses, especially Load Dump Tests Other than ISO - Coupling on IO & Signal Lines Direct coupling with AN for Example: GMW 3100GS Pulse 7a/7b VW TL82066 Pulse 6 Tests Other than ISO - Dips and Drops Details using DS 5630 AUX SOURCE + AUX SOURCE - Switch (MOSFET) MAIN SOURCE + EUT OUTPUT + Transient Protection MAIN SOURCE Reverse Voltage Protection and Buffer Capacitor EUT OUTPUT - Others Conducted Sine Waves and Ground Shift Others Magnetic Field Immunity Immunity to (low frequency) Magnetic Fields (Power Magnetics) Two different types of coils are supported by Autostar and NSG 5600: Radiating Loop: According MIL 461 (most often referenced test method) GPIB Battery Control Helmholtz Coil: Alternative method Main Source Main Source Battery Lines Control Unit Main In CT 5610 FG 5620 TC 5650 PA 5640 DS 5630 Aux In Main Output NSG 5600 PA 5840 / PA 5740 Radiating Loop Coil or Helmholtz Coil Typically Loop Coils cover a very large field range. The Loop Coil can be used for every DUT size. If Helmholtz Coils are used the coil size determines the DUT size. Immunity to (low frequency) Magnetic Fields (Power Magnetics) Helmholtz Coil (High Test Volume but Lower Field Strength) Radiating Loop Coil (Large DUTs may require multiple tests, but much higher field strengths possible) Immunity on Signal Lines ISO 7637-3 Pulse Immunity on Signal Lines Overview Generally, there are three ways to couple pulses onto signal lines: Wire Bundle: Capacitively with a Clamp or Jig Wire Bundle: Inductively with a BCI Clamp Individual Wires: Capacitively using Capacitors Pulse Immunity on Signal Lines “Slow Pulses” ICC Method Signal Lines U Equivalent to Pulse 2a (Negative) I DUT 0 Equivalent to Pulse 2a t Inductive Coupling Clamp (BCI Clamp) DCC Method - Signal Lines + 470 pF 470 pF DUT Ground Plane MT 5511 Inductive Coupling Clamp Method “Slow Pulses” BNC Output MT 5511 INA 5580 Coax cable PA 5x40 or battery (max 50cm) Control/ Peripheral CIP 9136 DUT Battery Lines Signal Lines Signal GND MT 5511 Inductive Coupling Clamp Method “Slow Pulses” ICC test setup according to ISO 7637-3 using Teseq equipment DUT, CIP 9136, and Control/Peripheral have to be placed on a insulating block (height 50mm) above the GND-plane.

Capabilities Overview NSG 5500 – Capacitive Discharge Pulse Immunity Generator Teseq has always been at the forefront of the automotive immunity test systems. The NSG 5000 was the first with systems based on a modular structure the NSG 5500 replaces it to now include an exclusive 100A standard compact coupler. Built on capacitive discharge circuitry, the NSG 5500 improves on the exclusive Gemini technology and expands on the unique pulse shaping qualities offering the only solution fully compatible with every immunity requirement from ISO 7637-2: 2004 NSG 5600 – Battery Voltage Variation and Noise Simulation Generator Teseq was first with automotive synchronized function generators with the NSG 5200. The NSG 5600 expands on the exclusive single-click programming interface and powerful event cloning features. Based on a function generator/amplifier combination, the NSG 5600 includes features for simulation of vehicle voltage starting profiles, dips and drops, transformer coupled and other sine wave noise and magnetic field immunity testing PA 5840 – Battery Simulating Power Amplifier Our battery simulators have always been market leaders. The PA 5840 expands on this with double the bandwidth, now in a modular and upgradeable rack-mountable version. Based on years of experience with fast automotive amplifiers, the PA 5840 now features an exclusive capacitive stability mode. Now users of Schaffner immunity systems can have it all: high current, very high peak inrush current, high bandwidth and stability with the difficult and varying loads encountered in automotive applications.

Do I have copies of these standards? Does it make sense to become an active member in the committee if the standard is a national or international standard? In these standards, what are the parameters of each test? Pay special attention to battery levels, tolerances, impedance, peak voltage, rise times and pulse widths. Do these tests have a verification procedure? Can my current equipment fulfil these (check it)? Is this standard scheduled to be changed soon? Can I upgrade easily if the standard is about to change? Do I have all the accessories I need? Load resistors, couplers, spacers, ground plane table cables, etc. Does my system have enough battery voltage or current? Does the battery simulator have enough bandwidth and/or a fast enough rise time? Battery Simulator Options Different applications require different sources AutoStar has a database which allows an operator to easily add a new source.
