摘要
Abstract
A 20 kV solid-state Marx pulse modulator is developed.The modulator is com-posed of eight-stage Marx modules in series,each of which adopts two independently con-trolled insulated gate bipolar transistors (ICBTs) for charging and discharging to its energy storage capacitor.It takes high voltage silicon stack for capacitor charging isolation and switch-driven isolation for each stage of the Marx module.With push/pull PCB structure, the Marx modules are easy to maintenance and replacement.Experimental results show that the 20 kV solid-state Marx modulator can generate output pulse with voltage more than 20 kV,pulse width of 10μs,raise/fall time of 300 ns at a load of 20 kΩ.Without strengthen cool,the pulse repetition rate is up to 1 kHz in burst mode.关键词
