To help curb climate change, the United States is rapidly electrifying many sectors of the energy economy, such as transportation (electric vehicles) and home heating (electric heat pumps). Thus, recent years have witnessed an explosion of businesses that want to connect and operate energy resources on the electric grid. However, getting an energy ...
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 varie...
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 lineari...
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 ...
This thesis details the design and testing of a reconfigurable battery array. Reconfigurable battery arrays, specifically for mobile applications, have the potential to reduce or eliminate use of auxiliary charging, balancing, and inverter systems. Design work included a bidirectional solid state switch and a cell-to-cell bidirectional current-limi...
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 en...
The project is a continuation of part 1 of the “Reliability Measurement for Grid-Connected Solar System” project. The goal is to continue where the previous design failed. This project will configure an ITECH IT-6000C and Tabuchi Battery Energy Storage System (BESS) to the small-scale microgrid at the Cal Poly, San Luis Obispo EE Department. Initia...
PolyWave Energy is the second team from California Polytechnic University at San Luis Obispo to compete in the Marine Energy Collegiate Competition. PolyWave Energy consists of Mechanical Engineering, Electrical Engineering, and Business Administration students who have worked together from September 2023 to May 2024 on designing, building, and tes...
Power electronics possess forms of non-ideality due to the nonlinearity present in physical switches. These switches are driven with pulse width modulation (PWM), which properly down-converts or up-converts based on converter topology. When these switches turn on or off, they introduce the main proponent of efficiency loss: harmonics. This becomes ...
The objective of this project is to provide a methodology to the electrical scope of mechanical leaf dryers. This dryer was particularly designed for an off-grid farm in New Longoro, Ghana in which resources and materials are limited. The electrical system must be designed so that it works with motors, variable frequency drives, worm gears, and oth...
