Research of high voltage RSDS triggering circuit in multi-modules capacitor discharge PFN for EML
In this paper, a compact pulsed power capacitor discharge module is considered to realize large current output for electromagnetic launching. A novel triggering circuit is proposed based on inductive adder circuit topology to provide optimal reverse current for controlling the high voltage RSDs assembly switching properly. Experimental results verified the IAT triggering circuit electrical and magnetic design.
New Generation of High - Power Semiconductor Closing Switches for Pulsed Power Applications
Summary form only given. A new generation of semiconductor closing switches based on reverse switched dynistors (RSD) has been developed to switch high-power current pulses with microsecond duration. In this report the results of theoretical and experimental investigations of RSD at peak current more than 500 kA and pulse duration up to 500 mus (at 0.1 Imax) are observed. The criteria of extreme peak current for switch taking into consideration the longtime performance under pulse-periodical mode are gave. The design and test results for switch under single pulse mode at operating voltage up to 25 kV and peak current up to 300 kA are described. The possibility of using such a switch in the ISKRA-6 capacitor bank is estimated.
Mathematical Time and Physical Time in the Theory Of Relativity
In the Theory of Relativity time is an imaginary quantity that can not be observed; it is a multiplication of a number that indicates duration of material change and number i that is an imaginary number. i on the square is -1. Time i⁄t is a mathematical time that describes the speed and the duration of material change. In the Universe one can observe physical time only as a stream of material change. It is not that change run in physical time, change itself is physical time.. Distinction between imaginary mathematical time and visible physical time opens some new perspectives into interpretation of Theory of Relativity. c
