Abstract

Since its integration into power electronic converters, the value proposition of wide band

gap semiconductors has yet to be holistically realized due to the high frequency effects associated with increased switching speeds. The United States Navy’s Smart Ship System

Design (S3D) platform enables the investigation of wide band gap-based devices in shipboard Medium Voltage Direct Current (MVDC) Integrated Power and Energy Systems

(IPES) through the use of metaheuristic model-based scaling laws. These physics-based

scaling laws are produced from a virtual prototyping approach which takes into account the

discrete building blocks associated with multi-cell based power conversion and distribution

equipment and can be used to predict size, weight, losses, cost and reliability. In present

practice, the discrete building blocks consist of power electronic assemblies laid out and

enclosed within shielded enclosures. In an effort to incorporate the high frequency effects

associated wide band gap-based Power Electronic Building Blocks (PEBB) into the virtual

prototyping approach, a mathematical model which captures the high frequency effects is

formulated in this thesis.
