DIRECT CURRENT GENERATION SYSTEM Russian patent published in 2015 - IPC H02P9/00 H02K21/12 

FIELD: electricity.

SUBSTANCE: direct current generation system comprises three three-phase armature coils [1, 2, 3] of the generator shifted in space relative to each other per angle of 2π/9, three three-phase rectifier bridge [4, 5, 6] with output leads [4.1, 4.2, 5.1, 5.2, 6.1, 6.2] and three-winding transmission filter [7] with windings [7.1, 7.2, 7.3] placed at rods (core legs) of three-phase magnet cores [7.4]. By their ends having the same polarity, windings [7.1, 7.2, 7.3] are jointed and connected to one output lead [8] of the system (positive in this case), while their other ends are coupled to outputs [4.1, 5.1, 6.1] of the same polarity (positive leads in Fig. 1) of three-phase rectifier bridges [4, 5, 6]. The other outputs of these bridges [4.2, 5.2, 6.2] (negative) having the same polarity are coupled to the second (negative) output lead [9] of the generation system. Each of three-phase armature coils [1, 2, 3] of the generator is connected to inputs of one of rectifier bridge [4, 5, 6]. Load [10] is coupled to output leads [8, 9].

EFFECT: reduced ripple amplitude of output voltage and improved dimensions and weight.
