Abstract:
Today’s state of the art additive manufacturing (AM) systems have the ability to fabricate multi-material devices with novel capabilities that were previously constrained by traditional manufacturing. AM machines fuse or deposit material in an additive fashion only where necessary, thus unlocking advantages of mass customization, no part-specific tooling, near arbitrary geometric complexity, and reduced lead times and cost. The combination of conductive ink micro-dispensing AM process with hybrid manufacturing processes including: laser machining, CNC machining, and pick & place enables the fa

A new hybrid diverter design for an On-Load Tap Changer (OLTC) is presented and experimentally validated. The design differs from existing semiconductor-assisted OLTC systems in that the part of the system containing semiconductor devices is connected in a purely shunt con guration to the main current path, resulting in a system that is electrically robust and very low loss. The new design provides zero-current, zero-voltage operation of both diverter switches at all times, eff ectively eliminating arc-induced contact wear.

This has an adverse effect on the manufacturability as well as the reliable operation of the system as a whole.

Eng., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, September, 2020<br>Cataloged from student-submitted PDF of thesis.<br>Includes bibliographical references (pages 77-80).<br>The quest for a suitable wide-bandgap semiconductor for high-power and high-frequency applications is well motivated; wide-bandgap semiconductors generally exhibit a high breakdown field and can therefore support a high voltage over short distances. Diamond (Bandgap of 5.5 eV) in particular is an attractive prospect since its thermal conductivity and radiatio

Abstract:
To enable the advancement of Si based technology, necessary to increase computing power and the manufacture of more compact circuits, significant changes to the current planar transistor are a necessity. Novel transistor architectures and materials are currently being researched vigorously. This thesis, on the electrical characterisation of non-standard orientated MOSFETs and multi-gate transistors displays detailed insight into the carrier transport and resulting performance limiting mechanisms. The results are composed of three parts. Firstly, the standard method of extracting carrier effect

Abstract:
This study investigates rapid changes in contact resistance, termed intermittences or short duration discontinuities, on tin-plated electrical contacts that are undergoing fretting tests. Voltage and current levels are comparable to the levels found in automotive systems. The thesis begins with an overview of the theory of mechanical and electrical contact, factors that determine the performance of an electrical contact and previous work on intermittences. Building upon this background information a low frequency fretting apparatus and a high¬speed data acquisition system are developed, capabl

Abstract:
In the last decade there has been increased interest in the study of molecular motors. Motor proteins in particular have gained a large following due to their high efficiency of force generation and the ability to incorporate the motors into linear device designs. Much of the recent research centres on using these protein systems to transport cargo around the surface of a device. The studies carried out in this thesis aim to investigate the use of molecular motors in lab-on-a-chip devices. Two distinct motor protein systems are used to show the viability of utilising these nanoscale machines a
