METHOD FOR CONTROLLING STATIC STABILIZED DIRECT CURRENT VOLTAGE SOURCES WORKING IN PARALLEL FOR COMMON LOAD Russian patent published in 2005 - IPC

FIELD: electric engineering.

SUBSTANCE: method includes forming voltage-setting signal, measuring voltage on common load and forming signal of negative check link on voltage by subtracting signal, proportional to voltage on common load, from voltage-setting signal, output current of each source is measured, signal for setting share of source current in common current of load is formed, signal for negative check connection on current is formed by subtracting signal, proportional to current source current, from signal for setting current source current share, and signal for controlling each source is formed, different by fact, that additional voltage signal is formed by integration of negative check link signal on voltage, control signal of one of sources working in parallel, in charge of voltage stabilization on common load, is formed by summing three components, one of which is proportional to additional voltage signal, second - proportional to negative check link signal, and third- proportional to output current of current source, said forming of signal for setting current share for each of remaining sources working in parallel is performed proportionally to current of source, adjusted by voltage, with proportion coefficient, equal to relation of nominal current value of current source to nominal value of current of voltage-adjusted source, for each of remaining sources an additional signal is formed by integration of its negative check link signal on current, and control signal for each of remaining sources is formed by summing three components, one of which is proportional to its additional current signal, second - to signal of negative check link on current, and third one is proportional to current share setting signal.

EFFECT: higher precision.
