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 1st 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. 1st and 2nd 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 1st and 2nd opto-triacs (20 and 21), respectively, as well as null-detector (22), saw-tooth voltage generator (23), comparator (24), 1st and 2nd pulse generator (25 and 26). ^ EFFECT: voltage stabilisation in asymmetric operating conditions. ^ 2 dwg |
