The invention relates to electrical equipment for electric trains. A converter consists of a synchronous generator (2) having an armature winding (3) and an excitation winding (4), a drive engine having an armature winding (5) positioned in slots (6) of a rotor (7), and a stationary inductor (8) on which are positioned an independent excitation winding (9) and a consecutive excitation winding (10). A rotor of the generator and a rotor of the drive engine are affixed to the same shaft (11). Outputs of the armature winding (5) are connected to a collector (12) which is located on the shaft of the rotor (7) near one end of the rotor, and are intended for connecting to a direct current voltage source by means of brushes (13). The rotor (7) of the drive engine is provided with a second collector (15) which is positioned on the shaft (11) near the second end of the rotor (7), sections of the winding (5) are made of two identical coils (16, 17) which are oppositely stacked in the slots (6) of the rotor (7) (Fig. 1), and the outputs of each of the coils (16, 17) are connected to a collector (12, 15) located on a corresponding end of the rotor (7). In each section of the winding (5), the coils (16, 17) are connected in series by means of the collectors (12, 15) and the brushes (13), with a shift of 180 electrical degrees. Currents, which pass through the conductors of the coils (16, 17) stacked in each slot (6), move in the same direction.

WO/2015/037971 HYDRAULIC DEVICES FOR PRODUCING ENERGY USING MOLECULAR FORCES OF LIQUID MOLECULES||WO||19.03.2015|
||PCT/LV2014/000008||GUZENKO, Vladimir Grigorjevich||GUZENKO, Vladimir Grigorjevich|
The present invention proposes using the internal energy of molecules, or, more specifically, the Van der Waals forces of intermolecular interaction of a liquid boundary layer, in order to produce energy. Said forces are extremely small and act in a microcosm, on the scale of molecules interacting only with molecules of the closest surrounding environment, the forces acting, in different directions, directly upon neighboring molecules. Only those liquid molecules which share a boundary with another medium (in a different state of aggregation) transfer their pressure strictly along the normal. This characteristic serves as the foundation for the proposed devices, which make it possible to produce a cumulative effect from the differently-directed and very small forces of a microcosm as a result of the strict orientation of liquid molecules in space. The liquid in the proposed devices is used not only as a working mass, but also as a "fuel". In producing energy, the internal energy of the liquid is consumed.
