PURPOSE:To stabilize the output current of a multioutput constant current converter by inserting a saturable reactor to each of a plurality of output circuits, connecting the control coils of the reactor in series and connecting the coils through the reactor to a DC power source. CONSTITUTION:Rectangulr wave voltages from the output coils 19, 20 of a transformer 2 are converted via saturable reactors 21, 22 to a rectangular constant current, and stable DC constant voltages ofIA=nAISR,IB=nBISR from the outputs A, B. In this circuit, even if one output is varied, the control currentISR of the saturable reactor 21 is controlled by a restriction choke 37 to eliminate the variation. Sice the other output current does not vary the control current, it is not affected by the influence of the variation in the other output current. |
