Nanosecond High Voltage Pulse Generator using Liquid Gap Switch for Compact High Power Pulsed Simulator
Shielding effectiveness test is a typical application of nanosecond high voltage pulse.A Compact High Power Pulsed Simulator for the shielding effectiveness is developed.To obtain fast rise time of pulse voltage,a switch has to have low inductance.A liquid gap switch has this property.This switch operates with fixed anode,cathode and a removable trigger electrode.The switch gap is filled with innocuous,fully biodegradable,and well insulating refined rap oil.By using the liquid gap switch,the voltage rise time is obtained approximately 1.8 ns and the peak value of the pulse electric field radiated by the simulator is more than 9 kV/m at 0.6 m in front of the antenna.Experimental results show that the best linear characteristics of peak value of the output voltage and maximum amplitude of the electric field.
