Dc-Dc 4-Switch Buck-Boost Converter For Energy Harvesting From Elliptical Machines, Alexander C. Samietz, Gustavo Guzman
Electrical Engineering
The senior project report documents the process of replacing the network of resistors inside an elliptical machine with a DC-DC buck-boost converter. The buck-boost DC-DC converter accepts a wide input range of 5-60 Volts, with an output of 36 Volts for the most efficient use of the already available microinverter. The microinverter reclaims the lost energy and safely distributes it back to the electrical grid. The addition of this project reduces heat emissions from wasted energy and shrinks the carbon footprint of its users.

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 …

Electrical Engineering
Create an efficient buck-boost converter that adapts to input voltage range from ~3.8V to 70V, and outputs 13.7V DC, the voltage required by a charge controller to charge a battery. The energy stored in the battery will be supplied back to the grid.
The cost of energy saved by the converter should eventually cover the initial price of the converter. The converter should help reduce the net power consumption of the exercise machines used in the Cal Poly gym
