  1. New solutions for automotiveEMC and supply simulation SPITZENBERGER+SPIES AND HILO-TEST

  2. Two specialist companies • HILO-TESTstarted business in 1978 and offers an extensive range of high-voltage test and measurement equipment portfolio.HILO-TEST is a pioneer in the EMC market.The CAR-TESTER was launchd in 2000. • Spitzenberger+Spiesoffers the most extensive Supply Simulation System portfolio in the world.The PASXXXX/GN/KFZ family was launcht in 1999. SPITZENBERGER+SPIES AND HILO-TEST

  3. The marketplace • Vehicle-Manufacturer • OEM-Manufacturerfor automotive electronics • Engineeringcompanys SPITZENBERGER+SPIES AND HILO-TEST

  4. The response • Compact Systems • Low power 20 ALowest test cost • High power up to 200 AHighest test quality and efficiency SPITZENBERGER+SPIES AND HILO-TEST

  5. Two companiesOne solution • Spitzenberger+Spies and HILO-TEST • PASxxxx/GN/KFZ and CAR-TESTER XX • Integrated Test Systemfor EMC and Automotive Supply Simulation SPITZENBERGER+SPIES AND HILO-TEST

  6. Transients inautomotive power systems • Test pulse #1This test pulse is a simulation of transient due to supply disconection from inductive loads; as used in the vehicle, it remains connected directly in parallel with an inductive load.Negative pulse 1/2000µs. SPITZENBERGER+SPIES AND HILO-TEST

  8. Transients inautomotive power systems • Test pulse #2This test pulse is a simulation of transients due to sdden interruption of current in an inductor connected in series with a divice under test.It simulates transients wich may for example occur due to the following: after the ignition is switched off, dc motors, wich are connected to the same swith as the ignition, may continue rotating due to their inertia, thus acting as generators. Their inductance creates a transient on swithing off the supply line.Positive pulse 1/50µs SPITZENBERGER+SPIES AND HILO-TEST

  10. Transients inautomotive power systems • Test pulse #3These test pulses are a simulation of transients, witch occur as a result of the switching processes. The characteristics of these transients ar influenced by distributed capacitance and inductance of the wiring harness.Positive and negative Bursts 5/100 ns SPITZENBERGER+SPIES AND HILO-TEST
