The Energy Harvesting from Exercise Machines (EHFEM) project at California Polytechnic State University consists of several different projects coming together to add human generated power to the grid. This project focuses on implementing a more efficient micro-inverter. The micro-inverter used to convert DC to AC voltage requires up to 5 minutes before the conversion process begins. This time lag significantly diminishes the power produced from an exercising individual. Research of micro-inverters approved by the CEC introduces desirable micro-inverters, available for use in California, to the EHFEM project. Testing the two most desirable micro-inverters found from research allows for quantifying of the most suitable micro-inverter. A new CEC improved micro-inverter aims to improve synchronization time as well as improved efficiency. This project finds improvement options in start up time and integrates the micro-inverter with the existing energy harvesting system to provide the grid with human generated energy.
