Dc-Dc Buck Boost Converter Using The Lt8390 Controller And Gan High Electron Mobility Transistors, Juan Manuel Urbano Jr, Brian Thongchai Keokot
Electrical Engineering
California Polytechnic State University, San Luis Obispo’s ongoing Energy Harvesting from Exercise Machines (EHFEM) project creates a sustainable energy source by converting physical exercise from exercise machines into renewable electricity. Implementing energy harvesting technology into the Recreation Center’s exercise machines helps Cal Poly make progress on its goal of carbon neutrality by 2050 [1]. An improvement to the system with new technology increases Cal Poly Recreation Center’s ability to save money and improve sustainability.
The focus of this project improves the design of Nicholas Serres, who used the LT8390 controller in his buck boost DC-DC converter [2]. This project improves …
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 …

Exercise Bicycle Dc-Dc Converter For The Energy Harvesting From Exercise Machines Project, Ryan Rickard, Logan Stowe
Electrical Engineering
Project is a continuation of previous projects that seek an efficient DC to DC converter for the existing exercise bicycle system created by Mechanical and Electrical Engineering students. This DC-DC converter is to integrate with the wide range of DC voltages produced by the bicycle in order to produce a constant optimal voltage for charging a car battery. This converter will boost voltages when the bicycle outputs below the optimal voltage and buck voltages when above. The converter will take EHFEM one step closer to its overall and final goal of harvesting energy from the exercise machines in Cal Poly’s …

Elliptical Machine Dc-Dc Converter For The Energy Harvesting From Exercise Machines Project, Greg Hollister
Electrical Engineering
Designing a DC/DC Converter for the Cal Poly Energy Harvesting from Exercise Machines project requires special attention to the unique operating characteristics of the source and the load. An elliptical machine powered by a person exercising comprises the source, while an AC Inverter makes up the load. This project attempts to integrate the two devices with a custom DC/DC Converter in order to ultimately deliver power back into the power grid.
