Abstract
A sporting apparatus comprises a structure body, an endless belt, an electricity generating unit, a position sensing unit and a modulation unit for continuously outputting electricity as the sporting apparatus is continuously operated. The electricity generating unit transforms kinetic energy, which is transmitted from the endless belt, into electric power. The position sensing unit senses a position of a user on the endless belt so as to generate a sensing signal. The modulation unit includes a DC/AC inverter, a current sensing element, an inductor and a semiconductor switch with a controller. The current sensing element senses an armature current outputted from the electricity generating unit and outputs a signal to the controller. The controller controls the duty ratio of the semiconductor switch to control the armature current, so that the armature current is adjusted according to the sensing signal for controlling the rotation speed of the endless belt.
