Development Of Multiple Input Single Output Dc-Dc Converter, Ryan Bailey, Miguel Carmona, Jose Velez-Lopez
Development Of Multiple Input Single Output Dc-Dc Converter, Ryan Bailey, Miguel Carmona, Jose Velez-Lopez
Electrical Engineering
This senior project report details the testing and validation of the designed DC-DC Multiple Input Single Output converter. The MISO uses four-switch buck-boost topology to output a single 48V from multiple nominal 24V inputs. The previous iteration of the MISO was plagued with an overheating mosfet that would drastically reduce the lifespan of the boards and reduce efficiency. This newest iteration includes more ground panes to combat the issues. In addition, the 200W MISO board was redesigned to utilize an edge connector for secure installment, removal, and replacement in the actual DC House system panel. The slots also have a …
Hybrid Ac/Dc House: The Road To A Sustainable Future, Nicholas Mcadams, Luis Rodriguez
Hybrid Ac/Dc House: The Road To A Sustainable Future, Nicholas Mcadams, Luis Rodriguez
Electrical Engineering
The Hybrid AC/DC house is a sustainable alternative to preexisting residential power systems. The implementation of a DC bus in current homes will allow inefficient DC-AC and AC-DC conversions to be circumvented. This provides a direct path for current to flow to DC loads from DC sources such as solar panels to minimize power losses. In doing so, this will give users the ability to power their homes strictly from renewable sources and substantially decrease reliance on the utility. For this purpose, the hybrid AC/DC house is also designed in such a way to be entirely grid-independent to provide power …

Making use of renewable energy directly from the location of production requires converting source power into usable power. The specific scope of this project focuses on the DC to DC conversion within a user friendly universal farmbot system. Since renewable sources vary widely in voltage and current, a wide input-range DC to DC converter is desired. Physical isolation, long lifespan, and adverse weather requires safe and reliable final product specifications. The goal of a very wide customer base drives the need for a product that does not require tinkering to get working, but to be usable out of the box …
Human-Powered Swing Generator, Danny Cai, Timothy Lai, Brandon Wong
Human-Powered Swing Generator, Danny Cai, Timothy Lai, Brandon Wong
Electrical Engineering
Many developing countries lack sufficient resources to provide enough electricity for every family to live with a satisfying level of comfort and convenience. Our project proposes a solution that provides families with an alternative access to electricity using a playground swing. This project addresses the design and construction of the Human-Powered Swing Generator, which converts mechanical energy to electrical energy for charging a battery. The charged battery serves as a source of DC energy for potential DC purposes, such as charging a cell phone.
Integration Of Pv & Simulated Dc Sources For The Dc House, Arvind Ramesh, Kevin Gingrich, Scott Chau
Integration Of Pv & Simulated Dc Sources For The Dc House, Arvind Ramesh, Kevin Gingrich, Scott Chau
Electrical Engineering
The DC House, an ever improving project, uses only pure DC power which most renewable energy sources generate, from solar to wind power. The DC House and this project expect a donation of photovoltaic modules to supply a constant source of DC power. At the moment, the DC House desperately needs power sources because not only does the house have various loads unaccounted for, but the distribution system to determine proper power flow needs a redesign. The project chose to account for these issues by implementing a solar panel onto the DC House and a power distribution module to have …
12 Volt Wall Outlet For The Dc House Project, Dylan Van Lant, Chenxi Zhang
12 Volt Wall Outlet For The Dc House Project, Dylan Van Lant, Chenxi Zhang
Electrical Engineering
The purpose of this project is to build a DC-DC converter for the wall outlet of the DC House. This report focuses on the development of the DC -DC converter, and explains the design process as well as summarize the final results. The proposed system using the Buck or Step Down topology takes input voltage of 48V and output 12V at 100W. Results show the ability of the converter to fulfill such tasks while maintaining efficiency about 90% at all load.

Dc House Model Design And Construction, Mark Cabaj
Electrical Engineering
Approximately 1.6 billion people currently live without electricity. The only sensible solution to their energy problems is the use of renewable energy in an off-grid, autonomous home which is powered directly by direct current, rather than alternating current coming from a power line, which probably cannot be found nearby. The purpose of this project is to construct a prototype of the DC House. More specifically, this project focuses on the development and construction of the power distribution system of the DC House. The system will be put in place starting from the source side model down to the load side …
Hydro-Electric Generation System For The Dc House Project, Dennis Kwan, Mitchell Krug
Hydro-Electric Generation System For The Dc House Project, Dennis Kwan, Mitchell Krug
Electrical Engineering
This paper focuses on the design, integration, and construction of a system that harnesses energy from flowing water. The system will be used in conjunction with the DC House Project. The proposed system employs a DC generator and DC-DC Boost-converter to provide electricity to the DC House at approximately 200-300W. Results of the testing and measurement show that the goal of the system is feasible, but currently limited. The generator could not output the specified power. Details of the design, along with ideas for further improvement, are presented in this report.
