Simulation of factors influencing on waveform of transmission line pulse

Transmission line pulse (TLP) can be used in immunity test of electrostatic discharge. Waveform of TLP especially its rising time is very important to the test. In the paper, Factors influencing on waveform of TLP are studied. A model based on principle of TLP is established. It´s then simulated. Influences of transmission line, relay, load and grounding wire on waveform of TLP are studied respectively. Two typical factors have been tested in a real TLP model to verify the simulation results. And suggestions improving waveform of TLP are given.
