Abstract: A power generation system includes a power generation unit, a power storage unit, and a voltage step-down unit. The power generation unit includes a generation main body having an electrification film and a counter electrode rotating relative to each other to generate power, and an energy generator generating energy for rotating the electrification film and the counter electrode. The power storage unit stores output power of the power generation unit. The voltage step-down unit is electrically connected to the power generation unit and the power storage unit and reduces output voltage of the power generation unit to a step-down voltage. The step-down voltage obtained by dividing the most energy-efficiently generated output voltage of the power generation unit by a step-down ratio of the voltage step-down unit coincides with storage voltage corresponding to a region between first and second turning points on a discharge curve of the power storage unit.
