DEVICE TO STABILISE AC CONTACTLESS GENERATOR VOLTAGE Russian patent published in 2009 - IPC H02P9/46 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and is designed to adjust AC voltage of contactless induction generators and induction generators with permanent magnets, incorporated with self-contained power supply system. Proposed device incorporates generator (1) with stator windings, each comprising three taps (2, 3, 4), windings starts (5, 6, 7), central winding leads (8, 9, 10) and winding finish. Note that winding starts are integrated and connected to the 1^st output of supply unit 16, central leads (5, 6, 7) and winding finish (8, 9, 10) are connected, via voltage stabilisation units (13, 14, and 15), with leads (17, 18 and 19) to connect generator load. 1^st and 2^nd three-phase excitation capacitor banks (11, 12) are delta-connected to leadouts of windings (8, 9) and (10). Outputs of power supply unit (16) are connected to voltage stabilisation units, each comprising 1^st and 2^nd opto-triacs (20 and 21), respectively, as well as null-detector (22), saw-tooth voltage generator (23), comparator (24), 1^st and 2^nd pulse generator (25 and 26).

EFFECT: voltage stabilisation in asymmetric operating conditions.
