FIELD: electromechanical engineering; off-line power supplies built around capacitor-excited induction generators. ^ SUBSTANCE: proposed stator winding has 18 coil groups. Finishing leads of coil groups k and (k + 9), where k = 1, 2, 3 through 9, are paired. Phase leads are taken from starting leads of coil groups 3, 9, 15 and constitute star connection; Additional phase leads constituting delta connection are formed from starting leads of coil groups 4, 6, 8, from integrated starting leads of coil groups 10, 12, 14, from integrated starting leads of coil groups 16, 18, 2, from integrated starting leads of coil groups 5, 7, from integrated starting leads of coil groups 11, 13, and from integrated starting leads of coil groups 17, 1. Field capacitors are connected to phase leads in compliance with desired power supply conditions of load. Such design of proposed winding makes it possible to obtain different voltages across generator output at fixed speed of drive motor. ^ EFFECT: enlarged functional capabilities of winding. ^ 1 cl, 8 dwg |
