DEVICE FOR REGULATION AND STABILISATION OF STANDALONE MULTIFUNCTIONAL ASYNCHRONOUS GENERATOR VOLTAGE Russian patent published in 2012 - IPC H02P9/46 

FIELD: electricity.

SUBSTANCE: generator contains LV stator winding that is Y-connected to the zero point outputs at one side and has first output pins for LV load and second output pins for HV load - on the other; to the said first output pins an additional power rectifier with "plus" and "minus" DC outputs and a HV winding are connected; connected to the HV winding phases is a bank of non-commutable capacitors; the three-phase electronic switch is designed in the form of an optoelectronic three-phase AC relay with the commutating voltage phase control via "zero"; the switch outputs and opto-coupler input are respectively connected to the bank of non-commutable capacitors and to the output of the comparator having a source of reference voltage with two additional resistances, placed in series; connected to the said resistances common point is the direct input of the comparator, its inverting input connected (via an additional potentiometer) to the output pins of the feedback rectifier, the latter input connected to the second output pins for HV load.

EFFECT: improved stability.
