The U.S. Army Research Lab ARL is investigating the switching capabilities of advanced silicon devices for high current pulsed power applications. These solid state switches are intended to replace more traditional vacuum switches. The benefits of these switches are higher dIdt, peak power levels and current densities, increased reliability and lifetime, and smaller switch volume. The peak current achieved by the device was 83.3 kA, with a 10 to 90 rise time of 3.5 microseconds while a 0.263 MA2s without failure. The peak power of the device during this test shot was 78.7 MW. ARL is collaborating with Silicon Power Corp. SPCO to evaluate Super-GTO performance and improve upon switchbuss bar packaging for pulsed power applications.
