(54) | DIELECTRIC ELASTOMER POWER GENERATION SYSTEM |
(57) A dielectric elastomer power generation system of the invention includes: a power
generation unit including a dielectric elastomer power generation element having a
dielectric elastomer layer flanked by two electrode layers; a step-down unit including
capacitors; a power storage unit for input of an output power from the step-down unit;
and a control unit that controls the connection between the step-down unit and the
power generation unit or power storage unit. The step-down unit includes first diodes
and second diodes, where the first diodes form a circuit that connects the capacitors
in series when the power generation unit is connected to the step-down unit, and the
second diodes form a circuit that connects the capacitors in parallel when the step-down
unit is connected to the power storage unit. This configuration serves to store the
generated power more efficiently in the power storage unit, e.g., a secondary battery.
