MULTIPHASE PHASE-FREQUENCY TRANSFORMER-REGULATOR Russian patent published in 2019 - IPC H01F29/08 H01F29/12 H01F30/16 H01F38/18 H02P13/10 

FIELD: electrical engineering.

SUBSTANCE: invention can be used, for example, in laboratory conditions for calibration of electric meters, for supply of consumers of multiphase voltage, critical to its frequency, etc. Multiphase phase-frequency transformer-regulator comprises housing, two axial magnetic conductors with slots, into which primary three-phase and secondary multiphase windings are laid, wherein axial magnetic core with secondary multiphase winding is made with possibility of rotation relative to fixed axial magnetic core with primary three-phase winding around their common axis of symmetry, and between the axial magnetic conductors there is an air gap, required for their mutual movement, wherein in upper part of housing there additionally installed correcting motor, shaft of which is fixed in bearing assemblies, and a phase and frequency setting corrector having first and second inputs, in the lower part of the correcting motor shaft, there are current-collecting rings arranged in the form of concentric circles and connected to the phases of the secondary multi-phase winding, and in lower part of housing sliding contacts are installed, wherein axial magnetic core with secondary multiphase winding is rigidly fixed on correcting motor shaft by means of disc, to primary three-phase winding is connected first input, and secondary phase-to-frequency corrector-phase corrector second input to secondary multiphase winding, output of which is connected to correcting motor input.

EFFECT: technical result is provision of possibility to control output voltage by frequency.
