Abstract

PURPOSE:To precisely protect a main control element or a load by connecting an auxiliary electric power source having comparatively large series impedance in parallel to a feedback signal to be compared with an output setting signal at the same polarity as the feedback signal. CONSTITUTION:An auxiliary electric power source 7 with the same polarity as an output current detector 4 and an impedance element 8 connected in series to the auxiliary device 7 are connected in parallel to the detector 4. A comparator 9 compares an output signal of an output current setter 6 with an output of the detector 4 and the differential output is inputted to a driving circuit 10. The connection rate of a main controlling element is determined by an output of the driving circuit 10.
