A 450-kJ pulsed-power supply (PPS) for electromagnetic launcher has been built up. It consists of six 75-kJ pulse forming units (PFUs). Each PFU is composed of a 75-kJ capacitor (1000 /12.2 kV), a thyristor stack as main switch, a diode stack as crowbar, a specific pulse-shaping inductor , and a coaxial cable. The peak value of the output current of one PFU is 85 kA with a peak time of 190 . The influencing factors of overvoltages on the series thyristor valves are studied by experiments and… CONTINUE READING
