Power Controller For Insulated Solar Electric Cooker, Ryan Koshy, Justin Tae-Hoon Kim
Power Controller For Insulated Solar Electric Cooker, Ryan Koshy, Justin Tae-Hoon Kim
Electrical Engineering
Insulated Solar Electric Cookers, or ISECookers, are devices created to aid those in impoverished regions improve safety, sustainability, and quality of life regarding their cooking practices. ISECookers present an alternative to traditional biofuel/biomass energy sources and provide a closed-loop, self-sustaining system that can be used in a variety of environments. These devices present solutions to widespread issues such as pollution, deforestation, and hazardous emissions as a result of traditional cooking in developing regions around the world. A notable obstacle of these devices is power delivery. Given the varying conditions experienced by a solar panel (inclement weather, irradiance irregularities, etc.), it …

Radio transceivers play a pivotal role in establishing communication networks, particularly in regions where existing infrastructures are unstable or compromised due to natural disasters or conflicts. By utilizing LoRa (Long Range) communication technology, OWL Integrations develops radio transceivers to establish mesh networks to communicate with one another during disasters. This project team continues development of a second generation OWL board, classified as Quacker Advanced Development (QuAD), with a focus on transitioning to a new microcontroller and integrating GNSS libraries and drivers. An ulterior objective involved R&D for a space application of the board.
A 4-Switch Buck-Boost Dc/Dc Converter For Electric Vehicle Applications, Andrew Hudak, Ashley Schiller
A 4-Switch Buck-Boost Dc/Dc Converter For Electric Vehicle Applications, Andrew Hudak, Ashley Schiller
Electrical Engineering
In this project, we develop a four switch buck-boost DC/DC converter that is to be integrated into a microgrid-inspired power distribution architecture for electric vehicles. The overall architecture includes DC/DC and DC/AC converters for bi-directional energy transfer between the DC and AC ports along with a communications port to control each energy interface. There is also the onboard battery and the internal combustion engine power exchange being done with DC/DC converters and AC/DC inverters to connect to the centralized DC bus. Hardware prototypes using an Arduino and Raspberry Pi for the 500 W DC/DC and DC/AC converters have been previously …
Design Of High Efficiency Doherty Power Amplifier, Kobi G. Kelly, Severin Pindell
Design Of High Efficiency Doherty Power Amplifier, Kobi G. Kelly, Severin Pindell
Electrical Engineering
The project includes design and fabrication of a high efficiency power amplifier for a student design competition held at International Microwave Symposium (IMS) 2023. Efficient power amplifiers are critical for base station communication requiring efficient use of available power. The final design optimizes power added efficiency (PAE) and linearity. The amplifier will operate at 2.45 GHz. Competitive PAE above 50%, and C/I above 30 dB is achieved by leveraging a Doherty class amplifier using accurate discrete CGH4006P transistor models to simulate an efficient and linear design. Unique design features include optimal transistor bias point selection and power split ratios between …
Ross Dam Micro Hydropower Project, Ryan Pospichal, Wilson Szeto
Ross Dam Micro Hydropower Project, Ryan Pospichal, Wilson Szeto
Electrical Engineering
In 2020, Utica Water and Power Authority (UWPA) commissioned the development and installation of a micro hydropower system for Ross Dam in northern California. The micro-hydro system was intended to serve as a reliable source of renewable energy to power on-site equipment for monitoring the Ross Reservoir. Despite its innovative approach, the system encountered operational shortcomings, including frequent mechanical failures, rapid wear, and an inability to adapt to variable flow rates. To address these challenges, UWPA has commissioned interdisciplinary teams of Mechanical Engineering (ME) and Electrical Engineering (EE) students to redesign the micro hydropower system. The ME team was entrusted …

X-Band Wireless Power Transfer System Using A Focused Array Lens, Jason Alexander Kunz, Tyler S. Bury, Oscar Damian Gonzalez, Jaime Garcia
Electrical Engineering
Wireless power beaming from space and energy harvesting were once stories of science fiction, until now. Wireless power transmission (WPT) is a field continually in development to provide energy in situations where energy transfer through wires is impractical or unfeasible. This engineering discipline abandons the use of wire technology for the energy transfer between the power source and a distant device. While various forms of WPT exist, our project focuses on transmission through means of radio frequency (RF), utilizing electromagnetic waves to power devices. Furthermore, WPT technology primarily assists in the elimination of a physical connection between devices, and it …

Improvements Of Hybrid Ac/Dc House Prototype, Arden Abude
Electrical Engineering
This is an iteration from previous designs of the Hybrid AC/DC House with a systematic addition of a portable AC power supply unit. This iteration for the Hybrid AC/DC House is an innovation of independence for sustainable housing solutions. It will serve as an alternative for rural communities needing power to rely on self-sustainable microgrids rather than large-scale AC electric grids. The addition of a portable AC power supply would allow the microgrid to remove its reliance on AC power from the larger grid and would elevate the system to complete energy independence. The microgrid has DC power generated from …
