FIELD: electricity.
SUBSTANCE: alternating-current generator includes a ferromagnetic ring mechanically connected to a rotation axis through traverses; one part is aligned with a saturating magnetic field of a strong constant magnet, and another part is related to a heat-evolving medium, for example purified water taken from the corresponding water pool. A controlled bias current source is connected with the output to a bias coil. A magnetic gap of the strong constant magnet is made of two parts, the first one of which forms a homogeneous magnetic field with intensity H* providing throughout length L of this part the achievement of a maximum value by magnetic susceptibility of the ferromagnetic, and the second one through length L forms a saturating magnetic field at the beginning of this part of the magnetic gap and then in the movement direction of a ferromagnetic ring the linearly increasing magnetic field as to intensity to the end of the magnetic gap. On the ferromagnetic ring there wound is a coil from a conductor, which is related to a storage battery through annular sliding contacts and a power diode in a charging circuit of the storage battery, which feeds the controlled bias current source, which are installed on its axis.
EFFECT: stabilisation of frequency of generated alternating current; improvement of reliability.
