CONTROL METHOD FOR VOLTAGE PULSE STABILISER Russian patent published in 2017 - IPC G05F1/56 

FIELD: electricity.

SUBSTANCE: invention can be used to control DC voltage pulse stabilisers of the step-up type with pulse-width modulation, which is connected to a power source of limited power that has the properties of a current source. The voltage at the output of the stabiliser is measured, a voltage error signal and its integral are calculated. By means of a differentiating element, the dynamic component of the output voltage is separated. At the beginning of each conversion period, the integral values of the voltage error signal and the dynamic component of the output voltage are stored. The stored values of the signals are multiplied by fixed coefficients, the results obtained are summed and the control pulses for the power electronic switch of the stabiliser is formed by the result of the summation on the basis of pulse-width modulation.

EFFECT: output voltage astaticism and a small output voltage ripple in the static mode, small amplitude and duration of transient processes in dynamic operation modes are provided in the pulsed stabiliser, it is possible to incorporate a control device based on microcontroller technology.
