METHOD FOR CONTROLLING CURRENT DISTRIBUTION IN A MULTICHANNEL PULSE CONVERSION SYSTEM Russian patent published in 2023 - IPC H02J9/06 

FIELD: electrical engineering.

SUBSTANCE: used for uninterrupted power supply of critical consumers from various power supply networks. Obtaining the resulting signal for the formation of pulse control signals in each channel as a result of the weight summation of the corrective current signal, as the difference between the output current and the average load current, as well as the corrective voltage signal, as the difference between the feedback signal and the reference voltage passing through a limiting amplifier, and a current feedback signal, defined as the difference between the measured value of the output current and the average load current passing through the threshold amplifier. At the same time, in the current overload modes, feedback suppression on the output voltage is ensured while maintaining the uniformity of the current distribution, both when stabilizing the maximum output current and when stabilizing the output voltage, which improves reliability, including for galvanically isolated conversion channels in conditions of power supply from various power supply networks.

EFFECT: uniform current distribution of galvanically isolated switching conversion channels connected in parallel at the output, including when limiting the output current while minimizing the boundary of the transition from voltage stabilization to current stabilization.
