Simulation and experimental study on inductance of low impedance pulse forming network

3D model of pulse forming network with 2.5 Ω impedance, 200 ns pulse width was established. Through the finite element analysis and simulation, the induction of the switch part and the load part was simulated and studied. The simulated results show that the induction was decreased with increasing frequency. The inner inductance of lead can be ignored when the frequency equal to 2.5 MHz. The inductance of lead is 10nH less in frequency 2.5 MHz than that in frequency zero. The simulated results also show that the mutual inductance can not be ignored when the switches work in parallel. In order to reduce the induction of lead, the configuration which isolates the switches was designed. The pulse rising time can be reduced 2 ns under the configuration. The experimental results indicate that t
