LINEAR GENERATOR OF BACK-AND-FORTH MOVEMENT Russian patent published in 2013 - IPC H02K35/00 

FIELD: electricity.

SUBSTANCE: linear generator includes fixed magnetic conductors and movable magnetic conductor. Movable magnetic conductor is made from carbon steel preserving the residual induction and has n salient poles along longitudinal and transverse axis, which are located in axial direction at the distance from each other, which exceeds the pole width by 3 times. Fixed magnetic conductors are located in pairs along longitudinal and transverse axis and have two windings each - excitation winding and generator winding that creates e.m.f. proportional to rate of change of flux linkage with frequency that is higher by n-1 times than frequency of back and forth movements. Generator windings are connected through diode bridge and thermal resistance to capacitor, thus charging it. Excitation windings are connected to capacitor too through a diode allowing the current to pass in one direction for creation of constant magnetic field.

EFFECT: simpler design and lower pulsations of rectified voltage.
