Abstract :
The Cannon Caliber Electromagnetic Gun (CCEMG) program at The University of Texas at Austin Center for Electromechanics incorporates two solid state switch modules. The 95 MW rectifier/inverter bridge (RIB) generates the field inside of the compulsator (CPA) and the 825 kA gun switch module (GSM) is the main closing switch between the CPA and the launcher. Since commissioning the CCEMG system, nearly 400 discharges have been performed using these switches. These tests produced a significant amount of information which will be very useful for the design of future solid-state switching systems on other electromagnetic launch programs. This paper presents the basic design, testing and lessons learned from the commissioning of the CCEMG system switches
