MULTICHANNEL PULSE CURRENT STABILISER (VERSIONS) Russian patent published in 2017 - IPC G05F1/56 

FIELD: electricity.

SUBSTANCE: multichannel pulse current stabiliser contains N power channels, feedback device and control unit connected to each other, and load which is activated between the consolidation point of 1-N channel outputs and common wire, the control unit is connected to the control input of each channel. Each channel contains an input filter, a key element, a transistor as a discharging key, according to the first version, and an output filter, consisting of a throttle and an output condenser. The inductance value is chosen based on the short time of the transient processes, the phases of the PWM-signals of channel control are shifted relative to each other by 2π/N. The condenser capacity is chosen to be minimal, while the duration of the period quarter of the LC-filter must be less than the maximum permissible duration of the leading edge of the pump pulse.

EFFECT: increased reliability and simplified pulse current stabiliser.
