MULTI-ZONE ROLL-OUT CONVERTER Russian patent published in 2011 - IPC G06G7/12 

FIELD: information technology.

SUBSTANCE: multi-zone rolling out converter has a first electrical power source, series-connected input signal source and roll-out amplifier, consisting of series-connected first adder and an integrator, the output of which is connected to a group of n main relay elements, where n≥3 is an odd number, the outputs of which are connected to a second adder whose output if connected to the second input of the first adder. The output of the fist electrical power source is connected to the roll-out amplifier and specifically to power terminals of the first and second adders, the integrator and power terminals of the main relay elements. The disclosed converter also includes an output stage consisting of (n≥3), where n is an odd number, extra optocouples connected in series to extra relay elements and a third adder, as well as a second electrical power source.

EFFECT: achieving complete potential isolation of the input-output channel, higher accuracy, noise immunity of the multi-zone roll-out converter and wider field of using said converter.
