A 40kJ, 20kV Electromagnetic Manufacturing (EMM) system [1] has been developed for forming and welding of various metals. The EMM consists of four energy storage capacitor based sub-banks, constant current charging variable dc power supply, single type spark gaps (TSG) switches. Four switches are used, one for each sub-bank. A trigger generator [2, 3] provides four simultaneous trigger pulses for...
In recent years, pulsed power systems have gained importance for the pulsed electron beam generation for industrial and defense applications. High voltage Energy storage capacitors were being used widely worldwide for the pulsed power system in electric field. In case of capacitive energy storage system, the size of the system is decided by capacitor size which depends on dielectric strength and relative...
In recent years pulsed power activity has gained wide spread importance in the field of defense & research. With involvement of energy storage capacitors, inductors, the generation, and consequent effective utilization of magnetic fields becomes inevitable in these spheres of research. Interaction process using magnetic fields has tremendous importance in every domain of physics. The present work...
This paper presents the experimental results of a repetitive Marx generator being developed at BARC. Effect of lead inductance, sparkgaps' alignment, charging inductor, ground inductor and shielding has been studied. Two types of configurations have been adopted in order to reduce the erected Marx inductance and results are compared. In this Marx generator plus-minus charging scheme was adopted for...
