Calculated Thermal Response of High-Power Switch to Short Pulses

Abstract

The U.S. Army Research Laboratory (ARL) has calculated the thermal response of a solid-state switch module to very short high-current, high-power pulses. A simplified model of the module was used in finite element simulations of heating in the eight silicon (Si) Super Gate Turn-Off Thyristors (SGTOs) in the module. Simulations calculated the temperatures of the devices in response to a series of pulses tens of microseconds ( s) wide in a span of 4 or 5 seconds (s). We calculated that the switch module could absorb several pulses in a brief period without increasing the temperatures to damaging levels.
