E1 Incidence Modeling Response of Solid-State Transformer Transistors

Understanding the potential vulnerabilities from future grid architecture is critical in developing resilient energy generation and transmission systems. This work investigated the response of a rectifier leg from a solid-state transformer to an early-time conducted high-altitude electromagnetic pulse. SPICE modeling of a single-phase representative layout of a 4leg rectifier was used to define the voltage and current behavior across the typical filter elements and half-bridge transistor elements to look for voltage conditions that may exceed damages thresholds of equipment. Results show that even basic, achievable filtering elements have a potential to significantly reduce the incident pulse impacts on rectifier transistors.
