Advanced propulsion systems for linear motion with high performance requirements

Creator:

Zhou, Xiaolin

Abstract:

Traditionally linear actuator applications are addressed by the use of hydraulic systems. The high maintenance cost and poor reliability will always be the most critical problem in the real applications. Benefited from both the high mechanical advantage of the roll screw and the simple structure of the switched reluctance motor,...

Dissertation
Evaluation of partial discharge in inverter driven medium voltage propulsion coils

Creator:

Ramme, André

Abstract:

Advancements in power electronics to higher power levels and faster switching times allow new machine and systems designs, but also create higher stresses on electric machinery insulation. High performance, pulse-width modulated (PWM) inverters are now available for medium voltage drive systems, and are being considered by the U.S. Navy as...

Dissertation
Novel power conditioning circuits for piezoelectric micro power generators

Creator:

Han, Jifeng

Abstract:

Advanced low power devices promote the development of micro power generators (MPGs) to replace the batteries to power them. Due to the trend in decreasing integrated circuit (IC) supply voltages, power supply designers are facing more and more serious challenges. The objective of this research is to design a power...

Dissertation
Scaled modeling and simulation of ocean wave linear generator buoy systems

Creator:

Gore, Ganesh P.

Abstract:

Accurate scaled modeling and simulation are critical to advancing ocean wave linear generator buoys. A 100th scaled model of ocean wave generator buoy systems is analyzed by solving the Navier-Stokes equations. These equations are numerically solved using Computational Fluid Dynamics (CFD) by implementing the front capturing method. In this thesis,...
