Abstract/Summary
In continuing the global effort to integrate innovative technology and renewable energy in the world’s power system, Cal Poly endeavors to harvest energy from elliptical machines and feed that power back into the electrical grid. This continuation of the previous project, Energy Harvesting from Exercise Machines Self‐generating Elliptical Machines, seeks an alternative DC to DC converter to function within the existing elliptical self‐generating system. By attempting to implement this new DC to DC converter, the project strives to reduce the size of the converter in order to mount it on the elliptical machine. The project also tries to explain how the chosen company‐manufactured DC converter works completely isolated. It also studies the DC converter behavior within the system when connected between the Precor elliptical machine and Enphase micro‐inverter. In developing this self‐harvesting elliptical machine, Cal Poly hopes to incorporate an array of energy‐harvesting elliptical machines in its REC center expansion slated for completion in 2012.
