An exercise bikes assisted main energy source in DC distributed power system

Abstract

The DC distributed power system for a house will facilitate the implementation of the small electric power sources from various renewable energies with less complexity connection and high efficiency of power sending. From these benefits, a human power generation based on exercise bike becomes feasible renewable energy. An electric energy is produced and sent to a DC distributed power system of the house only pedaling period. The voltage level of human power generated is maintained equal to a voltage level of the DC distributed power system. The retarding torque level setting by a cyclist is a value of a generator current that produces and sends to the DC distributed power system. From the experiment of results, they can send the electrical power to the appliances with the efficiency more than 99% and also assisted partial energy supplying in the main energy source such as 125w with a set of exercise bike unit and 252W with 2 sets.
