FIELD: transforming engineering, applicable for control of impulse DC voltage stabilizers of the step-up type with pulse-length modulation, which are connected to limited power sources possessing properties of a current source.
SUBSTANCE: current 
of the capacitor of the output filter and voltage 
at the stabilizer output are measured. Error signal 
where 
-standard voltage is amplified by 
times and integrated, limiting range of probable variation of the integral (stopping the integration)according to the values of its maximum deviations in dynamic operation not resulting in interruption of modulation. Capacitor current 
is amplified by 
times, subjected to frequency correction and in the sum with the integral of the error signal is fed to the modulator input. The sawtooth reference voltage of the modulator is formed as a quadratic parabola.
EFFECT: provided small amplitudes and duration of transient processes and astatism of output voltage.
