Capacitors for pulsed power systems

Experimental models of capacitors meant for using in directly operated pulsed power systems with energy supply time to load of 500 ns have been designed. It is supposed that the capacitor with energy output of 20 kJ would be rather perspective used as an elementary unit in such systems. At present time, an intermediate model HCEIcap50-4 is being tested and prototype units HCEIcap100-2 have been manufactured. Capacitors consist of plain sections of 2,5 m in length. The sections have a combined insulation, i.e. paper-film insulation with paper and mylar film. The expected characteristics of HCEIcap100-2 are as follows: capacity is 2µF, voltage is 100 kV, current is 1 MA. The results of the first static testing are presented. A specially adapted for the capacitor low-inductance switch to form a unitary high-current module is being developed.
