Cal Poly’s ongoing Energy Harvesting From Exercise Machines (EHFEM) project proposes sustainability and energy saving costs through modifying exercise machines generating DC power, providing a renewable energy resource through physical exercise. The EHFEM project contains multiple sub-projects involving modifying several different exercise machines. Each machine generates DC power and an inverter converts this power to AC. This AC power returns to the grid. This project addresses an issue involving a previously installed DC-DC converter not returning power properly. When generating DC power, the grid demands a specific AC voltage, but the generated power through the previous DC-DC converter and power inverter encountered several problems. One previous converter outputted the desired DC output, but at the cost of low efficiency (
