Embodiment Construction

[0013] The present invention will be described below, taking a system for generating electric power as an example. figure 1 The system shown in includes a thermodynamic part 10 with a working medium and a linear part 12, and a controller 14 acting on both parts.

[0014] The main components included in the linear section 12 (see also figure 2 and 3 ) is on the one hand a single-stroke “engine” with a linear expansion device in the form of a piston / cylinder unit 16 and on the other hand a linear generator 18 with magnets 20 and coils 22 . The piston / cylinder unit 16 basically consists of a pressure cylinder 24 and a piston 26 which is replaceable therein and which is coupled to the magnet 20 of the linear generator 18 . The first working chamber 28 of the pressure cylinder 24 is formed on the side of the piston 26 facing away from the magnet 20 , and the second working chamber 30 is formed on the side of the piston 26 facing the magnet 20 .

Abstract

A device for conversion of thermodynamic energy into electrical energy, comprises a piston / cylinder unit (16), a generator (18) and a controller (14). The piston / cylinder unit (16) comprises a pressure cylinder (24) and a piston (26) arranged in the pressure cylinder (24) linearly displaceable by the volume change of a working medium. The generator (18) comprises a coil (22) and a magnet (20). The magnet (20) is coupled to the piston (26) such that a linear displacement of the piston (26) brings about a linear displacement of the magnet (20) within the coil (22). The controller (14) controls the working stroke of the device depending on at least one measured process parameter.

Description

technical field [0001] The invention relates to a device for converting thermodynamic energy into electrical energy. Background technique [0002] There are many ways of generating electricity from mechanical energy of motion involving different efficiencies. In most cases, a generator that transforms rotational motion is used. However, such periodically operated machines achieve satisfactory efficiency only at a certain minimum frequency (rotational speed). When the energy supply is not constant, the energy conversion efficiency is very low. A reduction in energy supply results in a lower rotational speed outside the optimum operating range of the machine. This is usually compensated by transmission, however this results in lower overall efficiency and higher costs. Switching the machine off and on again does not solve the problem satisfactorily due to the associated wear and tear. [0003] Distinct approaches for generating electricity from kinetic energy are availabl...
