Abstract
Recently a compact and lightweight pulsed power generator, which can generate nanosecond scale high voltage pulse at high repetition rate is required for application of nonthermal discharge at atmospheric pressure. An inductive energy storage pulsed power generator with SOS (semiconductor opening switch) has a possibility of realizing the compact and lightweight pulsed power generator. The operation of the inductive energy storage system is divided into to three stages. On the first stage, the energy is stored to the primary energy storage capacitor. A portion of the energy is transferred to the inductor, and stored as an inductive energy. On the second stage, the high voltage pulse is generated by the current interruption of opening switch, and the inductive energy is transferred to the load. On the third stage, the final one, the energy remained at the primary energy storage capacitor, is transferred to the load after the transferring of inductive energy. In this research, the fundamental characteristics of pulsed power generator are investigated experimentally in concerning about above three stages of operations
