FIELD: electrical engineering; off-line dual-voltage power supplies built around capacitor-excited induction generators. ^ SUBSTANCE: proposed single-layer winding of double-pole induction generator has six coil groups; finishing lead of coil group 1 is connected to that of coil group 4, finishing lead of coil group 3, to that of coil group 6, finishing lead of coil group 5, to that of coil group 3; high-voltage phase leads are brought out from interconnected starting leads of coil groups 2 and 3, interconnected starting leads of coil groups 3 and 5, and from interconnected starting leads of coil groups 6 and 1; low-voltage phase leads are brought out from interconnected finishing leads of coil groups 1 and 4, from interconnected finishing leads of coil groups 2 and 5, and from interconnected finishing leads of coil groups 3 and 6; field capacitors are connected to high-voltage leads. ^ EFFECT: enlarged functional capabilities due to ability of dual-voltage power supply. ^ 1 cl, 3 dwg
