FIELD: electricity. ^ SUBSTANCE: invention relates to electric engineering, to conversion equipment, and may be used in devices of power supply of radio electronic equipment, comprising pulse voltage converters with application of transformers. Method to reduce saturation of pulse converter transformer consists in formation of signal proportional to current of transformer magnetisation and formation of control signal, correcting mode of transformer magnetisation. Formation of signal proportional to magnetisation current is carried out by detection of available values of voltage of straight and reverse half-waves of output voltage period and summation of these values. Control signal is used to correct off-duty factor of converter pulses. ^ EFFECT: reduced saturation of pulse converter transformer. ^ 6 cl, 2 dwg |
