The thesis provides insights into important modeling techniques to model the converter system, machine design, control and power stages and integration of the various sub systems to simulate the system level performance. This innovative modeling and simulation project is very relevant to optimizing the system performance, designing the sub circuits, components selection, predicting the system stability and impulse responses. The thesis presents modeling and simulation of three different 270VDC converter systems and comparing their performances against each other. The 270VDC converter system accepts either Generator 3-phase AC voltages or fixed three voltage source followed by single or dual converter stages depending on different topologies. The models developed for the high voltage DC systems are optimized to provide robust controls, close loop regulation and transient performance without any algebraic loop by employing valuable modeling techniques. The detailed modeling approach significantly minimizes the development cost by having the model representation of the actual system before the prototype development to ensure 'first time right' designs. The system model developed on industry common software platforms establishes the 'boiler plate' to allow the new systems to be modeled simply by delta changes on the base systems.
