Abstract
A power generation system includes a first power generation apparatus and a second power generation apparatus outputting alternating voltages by an input of vibrations; a first voltage-doubling rectifier circuit not only rectifying the alternating voltages output by the first power generation apparatus to store electricity, but also outputting enhanced voltages to the load instrument; a second rectifier circuit rectifying the alternating voltages output by the second power generation apparatus, and connected in series to the first voltage-doubling rectifier circuit, thereby outputting rectified voltages to the load instrument; a constant-current circuit connected in series to the load instrument, thereby limiting currents flowing to the load instrument to a predetermined current or less.
