Simulation Research on Pulsed Power Supply Sequence Solution Strategy Based on Charge Equivalent

To meet the requirements of the electromagnetic rail launch system for a large-scale pulsed power supply to output stable discharge current, seeking a fast solution method for the discharge sequence and obtaining a reasonable triggering sequence is a key direction of research on large-scale pulsed power supply. This article proposes a sequence solution strategy based on charge equivalent. Based on the principle of equal charge amounts during the discharge process, the relationship between the current waveforms and the number of modules at different stages is obtained. Then, the triggering sequence of each module is solved according to the set current requirements. A typical representative system was established to verify the feasibility and accuracy of the above solution strategy. The results show that the triggering sequence obtained by the solution strategy can make the discharge current meet the requirements and improve the solution efficiency. The sequence solution strategy based on charge equivalent can not only avoid complex mathematical calculations to obtain the triggering sequence, but also effectively improve the discharge success rate of the engineering test.
