Coltage transient emission

1. Introduction to the test

　　In the circuit design of automobiles/construction machinery, all circuits are powered by batteries and connected in parallel. When the switch of the EUT is powered on or off, it will produce transient conduction emission, which will affect the normal operation of other electronic devices in the parallel circuit. The transient emission test is based on the ISO 7637-2, E/e Mark (2004/104/EC, ECE.R10) test for the transient conducted emission of automotive electronic and electrical components along the battery power supply line or switching power supply line.

slow pulse

The EUT is far away from the switch, and the outgoing pulse is milliseconds or slower

fast pulse

The EUT is close to the switch, and the external emission pulse is nanosecond to microsecond level
