The comparator 4 outputs a signal of low level when the detected current value is smaller than a reference value 0. An AND gate 5 takes the logic product of the output of the comparator 3 and a drive command, and an OR gate 7 takes the logic sum of the output of the gate 5 and the output from a timer 6. Further, the logic product of the output of the gate 7 and the output of the comparator 4 is calculated by an AND gate 8, which produces an ON pulse producing signal of a gate driver 1.
