STABILISED ELECTRIC MACHINE POWER SUPPLY SOURCE Russian patent published in 2013 - IPC H02P9/30 H02P9/34 

FIELD: electrical engineering.

SUBSTANCE: device contains a synchronous generator with stator and excitation windings, a rectifier connected to the stator winding, a voltage sensor connected to the rectifier output pins, a voltage setting device, a control circuit and a device for rigid negative feedback; included in the control circuit are additional connected element: a comparison unit, a regulating device, a key element, a reverse diode; additionally introduced are a sensor of excitation current in the excitation winding circuit, a device for isodromic (flexible) negative feedback; functionally. The device is intended for transmission of excitation current oscillations as may occur from the excitation current sensor output to the third input of the comparison unit without phase shift.

EFFECT: damping excitation current self-oscillations and fast quench of the generator output voltage LF modulation.
