METHOD TO CONTROL STABILITY OF CONVERSION FACTOR FOR DIFFERENTIAL-TRANSFORMER CONVERTER Russian patent published in 2015 - IPC H03M1/10 

FIELD: electricity.

SUBSTANCE: method to control stability of conversion factor for differential-transformer converter (DTC) is featured by inclusion of output signal generation as ratio of difference of voltage drop at secondary DTC windings to their sum, at that internal resistance of the stabilized power supply source of primary DTC windings is selected so that at certain frequency of power supply within the whole temperature range of DTC operation sum of voltage drop at secondary windings U₁+U₂ of DTC is constant, at calibration primary DTC winding is fed with this source, sum of voltage drop U₁+U₂ is measured, this value is recorded, sum of voltage drop U₁+U₂ measured at secondary windings during DTC operation U₁+U₂ is compared with measured and recorded sum of voltage drop U₁+U₂ measured at secondary windings during calibration.

EFFECT: implementation of operability control for differential-transformer converter and stability of its metrological performance.
