CONTROLLED D C REGULATOR Russian patent published in 1994 - IPC

FIELD: electrical engineering. SUBSTANCE: controlled D C regulator has power regulator connected via current pickup to terminals for connection of load. Controlling input of power regulator is linked through analog storage to output of D C amplifier which input is connected to output of current pickup manufactured in the form of measuring unit with balancing of D C ampere-turns. It includes measuring winding linked to leads-out of current pickup, compensation winding composed of N separate sections with different number of turns, detector of unbalance of ampere-turns which output is used as output of current pickup. Regulator includes source of standard current and digital change-over switch composed of changing-over cells. Regulator also has unit for connection with computer, threshold current element, univibrator, supplementary changing-over cell, resistor and power transformer with primary and N+1 secondary insulated windings. EFFECT: enhanced reliability of regulator as compared with prototype. 5 dwg
