I also dedicate this thesis to our pets who are part of all our families, in particular our cats Tweedledum, Cheese and Joey, and our dog Cassie who made numerous trips to my desk in the course of writing this thesis, offering their unending love and affection. 5 ABOUT THE AUTHOR I enrolled in the Emergency Management M.S. program at University New Haven in January 2019 after retiring from full time employment at Roush Industries, Inc. as a Senior Engineer since 2007. Prior to joining Roush, I retired from Ford Motor Co. after 30 years of service since 1976 as a Principle Research Engineer and Product Development Supervisor. My background entering the program at UNH was a B.S. and M.S. in Mechanical Engineering, and a M.S. in Electronics and Computer Control Systems Engineering. My former work areas were in engine/powertrain systems design and development with Six Sigma black belt training. I deeply appreciate this opportunity offered to me at the University of New Haven to facilitate this career change in Emergency Management, and I hope it leads to many more years of work serving the public in disaster response, recovery and mitigation planning. 6 ABSTRACT A vulnerability exists in the U.S. to an attack from a nuclear weapon of mass destruction (WMD) optimized to generate an electromagnetic pulse (EMP) with potential for widespread damage to electrical components in the critical infrastructure including non-military (non-MIL) transportation sector vehicles. The purpose of this study was to develop a plan on how hazard risks from an EMP attack can be better understood for modern-day, “electronics-heavy”, transportation sector vehicles leading to affordable mitigation countermeasures that could be implemented as part of an emergency management plan. The FY2020 National Defense Authorization Act (NDAA) and preceding executive order signed by the President in 2019 supported this investigation to find ways to strengthen the transportation sector vehicle critical infrastructure from an EMP strike. A threat assessment analysis was used to identify capabilities of state actors and terrorist organizations that are of concern in national security forums. The hazards risk analysis utilized a hybrid emergency management/engineering approach to help visualize critical vehicle electronics sub-systems and components, and their respective potential failure modes. A comprehensive test plan was designed for modern-day, non-MIL transportation sector vehicles to identify the hazard risks which was accompanied by a failure modes and effects analysis template (FMEA) to quantify risks and prioritize mitigation countermeasures. Data from the literature from past testing, EMP resilience technical standards, and product information from expert suppliers who market EMP mitigation hardware were utilized to develop affordable mitigation countermeasure proposals for initial testing. The proposed emergency management plan was based on a strategic implementation of EMP mitigation countermeasures on non-MIL transportation sector modified to become resilient to EMP to support continuity in emergency services and delivery of lifeline supplies to the public after an EMP attack. A methodology was developed for enhanced logistics systems to address repair of un-modified, “as-built” vehicles

  • High Isolation Flyback Transformer Technical Article
    HIGH ISOLATION VOLTAGE FLYBACK TRANSFORMER By: Edgar C. Taculog Field Application Engineer, Asia TT Electronics New TT Electronics AEC-Q200 qualified and certified transformers are optimized for use with a gate- drive optocoupler to improve and simplify the design of isolated power supplies. Overview Transformers can often provide an inexpensive solution for a variety of applications. The purpose of the transformer is to isolate the secondary side of the circuit from the primary power source, transfer power efficiently from the electrical source to the target load and protect users from hazards like electric shock, fire and heat. The flyback transformer, which is an isolated version of a buck-boost transformer, does not in truth contain a transformer but a coupled inductor arrangement. When the transistor is turned on, current builds up in the primary and energy is stored in the core, this energy is then released to the output circuit through the secondary when the switch is turned off. The basic concept of this scenario can result in significant heat generation if not properly addressed.

  • How to Select a Surge Diode
    Application Report SLVAE37–January 2019 How to select a Surge Diode Alec Forbes ABSTRACT For systems in harsh industrial environments, one of the most important parts of system protection is the input TVS diode selection. The input TVS diode is designed to protect fragile system inputs from large transient spikes that are caused by nearby machinery, lightning strikes, or power surges. These surges are modeled and regulated by IEC 61000-4-5, which standardizes the protection requirements systems must meet in order to ensure that they will not see failures when exposed to these transients. However, passing these standards is not trivial, especially to a designer who is unfamiliar with protection diodes and the specifications. This document will provide an introduction to TVS diodes, comparing them to other transient protection solutions, discussing some of the key specifications and then providing a system example. An understanding of these specifications will allow a designer to have a more solid fundamental understanding of how to select a TVS diode for surge protection, which will directly translate to a more robust system.
