Hence, I wish to express in words my deepest gratitude to my adviser, Professor Osama Mohammed, for his guidance, encouragement, and support during my graduate study. His creative thinking, knowledge and expertise on computational electromagnetic were indeed the fuse of my propulsion motor in conducting this research. I would like to thank my dissertation committee members Professor Sakhrat Khirzroev, Professor Ibrahim Tansel, Professor Jean Andrian, and Dr. Nezih Pala for their insightful comments and constructive suggestions in the review of my research proposal and dissertation. I would like to acknowledge the partial research support provided from the office of Naval Research and the US department of Energy throughout my years of research in Energy Systems Laboratory. I also acknowledge the doctoral DEA fellowship from FIU graduate school during the summer semester of 2013 of my studies at Florida International University. Although this doctoral dissertation is considered to be my personal accomplishment; I would like to acknowledge my colleagues in Energy Systems Research Laboratory for their creative support, encouragement, and collaborations during my graduate studies. I also appreciate the trust and support of the ECE Department staff; Ms. Pat Brammer, Ms. Ana Saenz, and Mr. Oscar Silveria during my studies in department of electrical and computer engineering. vi ABSTRACT OF THE DISSERTATION The low-frequency electromagnetic compatibility (EMC) is an increasingly important aspect in the design of practical systems to ensure the functional safety and reliability of complex products. The opportunities for using numerical techniques to predict and analyze system's EMC are therefore of considerable interest in many industries. As the first phase of study, a proper model, including all the details of the component, was required. Therefore, the advances in EMC modeling were studied with classifying analytical and numerical models. The selected model was finite element (FE) modeling, coupled with the distributed network method, to generate the model of the converter's components and obtain the frequency behavioral model of the converter. The method has 10.
