Experiment on MOSFET solid state switch

The key technologies of building a high repetition rate solid state switch were studied with two power MOSFET components, two MOSFET drivers, and fiber as high voltage isolator and optical data link. These technologies are trigger signal high voltage isolation technology, power MOSFET drive technology, power MOSFET parallel link and series link technology. Outputs of 1kV, 13A, 4MHz repetition rate on single MOSFET switch, 1.6kV, 2MHz repetition rate on two series MOSFET switch,and 130A, and 2MHz repetition rate output on two parallel MOSFET switch have been got．
