Two circuit model extractors for complex multilayer microelectronic packages based on the Partial Element Equivalent Circuit (PEEC) technique, namely University of Arizona Effective Package Inductance Calculator (UAEPIC) and University of Arizona Effective Package Inductance and Capacitance Calculator (UAEPIC²), have been developed. The first one, UAEPIC, is based on the magneto-quasistatic assumption where the displacement current effect on the derivation of the electromagnetic field integral equation is neglected and thus the dominant inductive effects are modeled in order to extract the RL

Existing risk simulations make the assumption that when a free tin whisker has bridged two adjacent exposed electrical conductors, the result is an electrical short circuit. This conservative assumption is made because shorting is a random event that has a currently unknown probability associated with it. Due to contact resistance electrical shorts may not occur at lower voltage levels. In these experiments, the effect of varying voltage on the breakdown of the contact resistance which leads to a short circuit was studied.

Abstract:
<div>Cables play an important role in the design of a power system. DC cable design presents unique challenges due to the fact that space charge can accumulate within the dielectric over time. Space charge accumulation is a function of temperature, electric field, and dielectric properties. Of particular concern is that the space charge leads to electric fields that are sufficient to break down the cable, particularly during transient conditions such as voltage reversal.</div><div><br></div><div>In this research, a focus is on the development of a coupled thermal- and electricalequivalent-circ

Abstract:
<div>The high-frequency switching of transistors in power electronic (PE) converters is known to cause unintended common-mode (CM) current that flows through parasitically-coupled ground paths. One way to model these currents is to utilize time-domain simulations that capture switching dynamics and the corresponding parasitic response. Although potentially useful, the small time steps required can create a computational burden and limit the usefulness of the approach. In addition, access to internal hardware needed to characterize parasitic parameters is often limited.</div><div><br></div><div

Abstract:
High voltage power transformers are designed to withstand a variety of overvoltages and short circuit forces. Occurrence of these events in a power system is natural, inevitable, and one of the main causes of transformer failure. Therefore, an early and reliable detection of an incipient fault is paramount. To this end, diagnostic testing and condition monitoring, not only enables power utilities in early detection of incipient fault-like conditions, but also is a practical way of optimizing existing assets, lowering operating costs, scheduling maintenance, preventing unplanned outages, etc. a

Abstract:
Longitudinal piezoelectric transducers (LPT), which collectively refer to piezoelectric actuators, vibrators, sensors and actuators designed for longitudinal deformations or vibrations, are the most widely used piezoelectric devices. LPT model, which can be used to predict the behavior or performance in time/frequency domain, plays a vital role in the design and optimization of these LPT-based applications. Existing models which can be used for dynamic behavior prediction, are based on the complex electromechanical coupled fundamentals of piezoelectricity, which involves a complex position-var

Abstract:
<p>Due to increasing regulation on emissions and shifting consumer preferences, the wide adoption of battery electric vehicles (BEV) hinges on research and development of technologies that can extend system range. This can be accomplished either by increasing the battery size or via more efficient operation of the electrical and thermal systems. This thesis endeavours to accomplish the latter through comparative investigation of BEV integrated thermal management system (ITMS) performance across a range of ambient conditions (-20 °C to 40 °C), cabin setpoints (18 °C to 24 °C), and six different
