Abstract：For pulsed power supply module of an electromagnetic railgun system, thyristors that have the excellent ability to withstand high voltage and high pulse current is always selected as the pulse discharging switch to reduce the volume and improve energy storage density. Existing literatures have extensively researched the dynamic opening process of thyristor and improved the accuracy of thyristor equivalent circuit model. This paper studied a special voltage oscillation phenomenon caused by high frequency resonance in main circuit during pulse capacitor discharge. Firstly, the mechanism of the voltage oscillation was studied according to the configuration of the main circuit. Further, circuit simulation was carried out to verify the correctness of the theoretical analysis above. Finally, a feasible method was proposed to eliminate the voltage oscillation. The related conclusions in this paper have certain practical significance for optimizing the pulsed power module used in electromagnetic railgun system.
