METHOD TO CONTROL PULSE VOLTAGE STABILISER Russian patent published in 2014 - IPC G05F1/56 H02M3/00 

FIELD: electricity.

SUBSTANCE: voltage U_out is measured at the outlet of the stabiliser, as well as inlet voltage U_in, currents of the throttle I_L, and load l, these signals are selected in each period of conversion at certain moments of time h; the signal "capacitor current" is calculated, its dynamic component is extrapolated, and to ensure static accuracy of output voltage of the pulse voltage stabiliser, they generate a mismatch signal by voltage, and its digital summation is carried out with accumulation (they perform digital integration); the signal "capacitor current" after frequency correction and in the sum with the integrated signal of mismatch is sent to the inlet of the width-pulse modulator.

EFFECT: increased quality of outlet voltage of pulse voltage stabiliser PV under dynamic and static modes of operation during discrete processing of its information signals.
