PULSE STEP-DOWN VOLTAGE CONVERTER WITH THE CURRENT STABILIZATION CONTROL METHOD (VARIANTS) Russian patent published in 2018 - IPC H02M3/156 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the electrical engineering, namely to the DC / DC impulse converters control methods, which are widely used for powering various devices in many fields of engineering. Stated task is realized by the fact, that in the first variant of the pulsed DC / DC converter with current stabilization control method, based on the control signal pulse width modulation by the key element, which consists in the fact, that in current control loop measuring the converter current actual value and obtaining the converter current actual value and its reference value loop error signal, summing the resulting loop error signal with signal proportional to the converter output voltage, and by the resultant signal generating the key element PWM control signal. In the second variant of the pulsed DC voltage converter with current stabilization control method, based on the key element pulse control signal width modulation, which consists in the fact, that in the current control loop measuring the converter current actual value, obtaining the converter current actual value and its reference value loop error signal, summing the received loop error signal with signal proportional to the converter output voltage by its input voltage division result, and using the resultant signal to generate the key element controlling PWM signal.

EFFECT: technical result consists in the converter output current stabilization, for which ensuring the converter to the voltage change maximum response speed.
