Abstract

PURPOSE: To ensure a quick current pressing even at the overcurrent time by installing the overcurrent detection reference setter, the level decider and the gain switch circuit and then reducing the gain of the gain switch circuit via the output signal of the level decider.
CONSTITUTION: The main circuit current value is extracted from current transformer 6 and then supplied to current-voltage converter 2. Then output Ef of circuit 2 is compared with overcurrent detection reference setter 8, and the level is decided through level decider 9. Decider 9 operates at the time point when the current more than the current equivalent to setter 8 flows, and then gain switch circuit 10 is actuated. At circuit 10 current reference signal Eref applied through current reference setter 1 is turned to KEref (K<1) and then led to constant current error amplifier circuit 3. Circuit 3 operates with KEref-Ef used as the input and functions to give a quick pressing to the overcurrent since it features the larger deviation component than ordinary input Eref-Ef. This means only that the constant current reference has changed from Eref to KEref, thus ensuring the steady constant current control.
