Pv Mppt Water Pump Controller, Jacob R. Lamkin
Electrical Engineering
The intention of this project is to create a low cost way to extract the maximum useful power from a PV module to power a water pump. This approach will yield maximum financial and technical accessibility for end users. The project was successful in powering a water pump from a PV module as desired, and the microcontroller driven control circuitry was capable of finding and maintaining operation at the maximum power point of the PV module. Due to the low performance of the buck converter used in this project, this approach was not as efficient as desired and would require …

The DC House USB-C Charger will convert the 48V input from the DC house, found on the Cal Poly campus, to 3 USB-C outputs: 5V, 12V, and 24 volts. The converter will deliver a total of 185 Watts out across all 3 outputs, with an efficiency greater than 82% at full load. The USB-C ports will be used to connect to compatible phones, laptops or any other device for charging/powering purposes. The goal of this project is to develop the most efficient and safe converter to deliver power to multiple outputs using USB-C, for items as small as a cell …
Dc-Dc Buck-Boost Converter For Energy Harvesting From Exercise Equipment, David T. Bolla
Dc-Dc Buck-Boost Converter For Energy Harvesting From Exercise Equipment, David T. Bolla
Electrical Engineering
This senior project helps harvest the excess energy that exercise equipment generates. Sustainable energy acts as the main target for this project, and it attempts this through reusing the energy created when exercising on elliptical machines. An elliptical machine outputs voltages between approximately 5V and 60V, and a micro-inverter requires an input voltage of about 36V. This DC-DC converter takes the variable output voltage of an elliptical machine and brings it to approximately 36V. Re-purposing the excess energy an elliptical user creates for the grid provides a sustainable alternative to dissipating the energy as heat. This project, along with other …

Despite the importance of electricity and the impact it has on our daily lives, many people around the world still live without this essential utility today. According to the International Energy Agency (IEA), approximately 1.1 billion people in the world did not have access to electricity in 2017. The DC House Project at Cal Poly aims to provide electricity to people living in rural areas by directly utilizing DC energy generated from renewable or human powered sources without the need for DC-AC conversions. However, one significant issue is the lack of a standardized DC wall socket. Standards for AC wall …
