DEVICE FOR REGULATION OF CURRENT RATIO IN LOADS Russian patent published in 1995 - IPC

FIELD: current regulation. SUBSTANCE: device has common current detector 3, (n-1) regulating elements 4, (n-1) corresponding current detectors 5, (n-1) operational amplifiers 6, which amplification ratio can be tuned, (n-1) differential amplifiers 7. Loads 2 are connected in series. Ratio of current running in each loading 2 to current running in first loading is regulated by control of amplification coefficients of operational amplifiers 6. Given ratio of currents in loads 2 is achieved by selection of amplification coefficients of corresponding operational amplifiers 6. These coefficients can be changed by control signals from computer. detectors 3 and 5 and insensitive to temperature. This results in possibility to achieve ratio of currents in loads 2 that is insensitive to temperature. EFFECT: increased precision of control regulation. 1 dwg
