Abstract
A power generation device that includes an excitation coil with a central opening, and a magnetic circuit extending through the central opening of the coil and including at least one permanent magnet and a plurality of ferromagnetic members arranged in a fixed portion and two mobile portions. The two mobile portions are mounted on two parallel rotary axes and can each assume two positions. The device further includes a mechanism rotating the two mobile portions between the two positions thereof so as to create two states of the magnetic circuit, i.e. a first state in which a magnetic flow flows through the coil in one direction and a second state in which a magnetic flow flows through the coil in the opposite direction.
