METHOD FOR CONTROLLING A SWITCHING VOLTAGE REGULATOR Russian patent published in 2022 - IPC H02M7/53862 

FIELD: converter technology.

SUBSTANCE: invention relates to a converter technology and can be used to control pulse-width-modulated DC voltage pulse stabilizers. At each period T of operation of the stabilizer in the vicinity of the moments of time t₀ - t₃, the controlled electronic switches are switched. The moment of time t₀ coincides with the beginning of the period T, and the moment of time t₁is formed according to the principle of pulse-width modulation as a function of the integral of the mismatch signal for the output voltage and the dynamic component of the output voltage U_out of the stabilizer. The times t₂ and t₃ depend on the time t₁, the inductance of the choke L, the input U_in and output U_out voltages of the stabilizer, the time t_c at which the choke current takes a negative value, some negative current I0 of the choke and the coefficient C_px and are calculated by the formulas:

t₂ = (C_pxT- t₁) U_OUT/U_IN = t₃ = t_c - LI₀/U_out.

EFFECT: small amplitude and duration of transients and astatism of the output voltage are provided.
