DEVICE CURRENTS-TO-LOAD RATIO CONTROL Russian patent published in 1995 - IPC

FIELD: electrical engineering. SUBSTANCE: device for currents-to-load ratio control has regulating element 2, two current pickups 3 and 4, inverting amplifier 5, operational amplifier 6 with controlled gain and differential amplifier 7. Leads of power supply source 1 are connected to loads 8 and 9. Gain factors K₁ and K₂ of amplifiers 5 and 6 are chosen from condition specified in description of invention. Choice of gain factors K₁ and K₂ provides for obtainment of specified ratio of currents in loads 8 and 9. Factor K₂ can change in agreement with program input from computer. Use of thermally stable current pickups 3 and 4 ensures obtainment of thermally stable ratio of currents in loads 8 and 9. EFFECT: increased accuracy of current control. 2 cl, 2 dwg
