Abstract

PURPOSE:To simplify the constitution of the titled device by a method wherein the converter obtaining DC voltage corresponding to the value of a current flowing to the load thereof from a DC supply source having a high current value is constituted by using resistors and an input differential amplifier. CONSTITUTION:A serially-connected body of resistors 7 and 8 is connected between the output terminal 301 of a shunt circuit 3 and the output terminal 102 of the DC supply source 1, while a serially-connected body of resistors 9 and 10 is connected between the output terminal 302 of the circuit 3 and the output terminal 102. Outputs obtained at connecting points of the resistors 7 and 8 and 9 and 10 are inputted in the input terminals 111 and 112 of a differential amplifier 11 respectively and the difference between two inputs is amplified. The input terminal 111 of the differential amplifier 11 is connected to a zero- potential source bus 12. By this constitution, an output voltage generated at the output terminal 5 of the differential amplifier 11 turns exactly to be the difference between input voltages impressed on the input terminals 111 and 112 even when an in-phase voltage impressed on the input terminals 111 and 112 is large.
