Study on solid state modulator based on power MOSFET devices

A solid state modulator with multi-pulse burst capability in mega Hertz, fast rise and fall times, pulse width agility has been designed and tested. The trigger system was designed by using MCU and CPLD. The experiment of six parallel MOSFET was done in print circuit boards which were elaborate designed and good result was obtained. The modulator uses three solid-state modules stacked in an inductive-adder configuration. When the charge voltage was 800V, we got output pulse with shortest width of 33.8ns, rise time of 13.9ns, amplitude of 2.20kV. Good experiment results in multi-pulse output were also obtained.
