MEASURING CONVERTER Russian patent published in 2007 - IPC G01R17/10 

FIELD: measuring technique.

SUBSTANCE: measuring converter can be used for measuring informative changes in active resistances under instabilities of power sources and resistances composing converter. Measuring converter has two primary converters turned on in differential. Converters are connected in series with power source and with third converter, which is made in for of resistor, for example. Device also has two measuring amplifiers, differential amplifier and division unit. Inputs of first measuring amplifier are connected with adjacent outputs of primary converters, connected in series, and with output of third converter. The third converter is connected to with one pole of power source. Inputs of second measuring converter are connected with second output of third converter, which converter is connected with corresponding output of one of primary converters and with output of the second primary converter, which is connected with second pole of power source. Output of first measuring converter is connected with direct input of differential amplifier. Inverting input of differential amplifier is connected with output of second measuring amplifier. Outputs of differential amplifier and of second measuring amplifier are connected with corresponding inputs of division unit. Output of division unit has to be input of measuring converter.

EFFECT: simplified design; improved precision of measurement; reduced number of members of measuring circuit.
