Abstract

The feeder circuit to which the present invention pertains comprises means for regulating which serves to feed an electric current to a positive output terminal and a negative output terminal; means for feeding electric current which serves to feed an electric current to the means for regulating; means for regulator control which serves to control the electric current output from the means for regulating; a first resistance located between the negative terminal of the means for feeding electric current and the positive output terminal; and a second resistance located between the positive terminal of the means for feeding electric current and the negative output terminal. The provision of the first and second resistances allows the median value of the potential at the positive output terminal and the potential at the negative output terminal to be controlled in such a manner as to ensure that it tallies with the median value of the potential at the positive terminal of the means for feeding electric current and the potential at the negative terminal thereof, while also absorbing any imbalance between the current at the positive output terminal and the current at the negative output terminal.
