Modular Electronic Load, Jason March
Modular Electronic Load, Jason March
Electrical Engineering
This project entails the design and development of a modular electronic load. The cost and simplicity of the design are considered such that it can be reproduced in-house to replace whenever possible resistor box for load testing of any analog circuits but more specifically power electronic circuits.
The design process as well as the hardware development is explained in details in this report. Results from hardware testing are also provided.

An Expandable Micromotor Dc Drive System, Michael Ruelan, Justin Gragg
Electrical Engineering
This report documents the design phases and fabrication of an expandable micro-motor DC drive system. This project illustrates that a flexible range of output power demands can be met from a small DC micro-motor drive unit with the use of power electronics.
In this project miniature DC micromotor drives, each capable of drawing up to 5.5 amps rated current (5 amps due to the utilization of a 5 amp fuse), were designed as card inserts that can be conveniently inserted in parallel in to a cardholder within the console. The “insert” feature allowed our console to successfully draw up to …

High Voltage Resonant Self-Tracking Current-Fed Converter, Scott Logan Mcclusky
Master's Theses
High voltage power supply design presents unique requirements, combining safety, controllability, high performance, and high efficiencies. A new Resonant Self-Tracking Current-Fed Converter (RST-CFC) is investigated as a proof-of-concept of a high voltage power supply particularly for an X-ray system. These systems require fast voltage rise times and low ripple to yield a clear image.
The proposed converter implements high-frequency resonance among discrete components and transformer parasitics to achieve high voltage gain, and the self-tracking nature ensures operation at maximum gain while power switches achieve zero-voltage switching across the full load range. This converter exhibits an inherent indefinite short-circuit capability. Theoretical …
