PROBLEM TO BE SOLVED: To provide an energy conversion device capable of displacing and operating a movable part, and improving energy efficiency.SOLUTION: An energy conversion device 1 includes: an oscillating power generator EH and a rectifier circuit 71. The oscillating power generator EH is configured such that a magnet block 3 and a coil block 4 can be relatively displaced in a specified direction orthogonal to an opposite direction, and that a movable part 12 having the magnet block 3 can be operated from the outside so as to be vibration-damped. The oscillating power generator EH includes: the movable part 12; a support part 14; and an elastic body part 15. The elastic body part 15 has rigidity which is smaller in the specified direction than in a direction orthogonal to the specified direction. At both sides of the movable part 12, a plurality of elastic body parts 15 are respectively disposed side by side. The rectifier circuit 71 is a voltage doubler rectifier circuit in which different capacitor C11 or C12 is charged respectively according as the polarity of an AC voltage to be output from the oscillating power generator EH is positive and negative. |
