The pulsed power consists of a voltage rise time of less than 50 ns and charging energy to 1.0 J/pulse; also, the pulse control area includes pulse interval pulse shot number, output voltage. To achieve this system, a pulsed power system exists including software running on PC, universal serial bus （UgB~ for connection, and FPGA controller. Using the software for complex control of pulsed power will enable expansion into various fields with easy operation.展开更多
