FIELD: reducing voltage ripples across power consumers incorporating rectifiers and inverters.
SUBSTANCE: proposed device has regulation channel, pulse source, series-connected voltage sensor, AC voltage component computing device, comparison gate, delta-modulator, and four-quadrant converter. Regulation channel has series-connected converter transformer, thyristor bridge, amplifier, and pulse distributor. Converter transformer input is connected to supply mains and pulse source output, to pulse distributor input. Voltage sensor input is connected in parallel with converter transformer primary winding and its output, to input of AC voltage component computing device and to second input of comparison gate; four-quadrant converter output is coupled with converter transformer secondary winding.
EFFECT: enhanced power output and mean time between failures.
