Title: Current controlled semiconductor element drive circuit
Inventor: KARAKI TOSHIRO
IPC: H03K17/56
Filed: 2000-09-08
Abstract: PROBLEM TO BE SOLVED: To provide a current controlled semiconductor element drive circuit suppressing the fluctuation of a gate voltage and preventing a transistor from being erroneously turned on without prolonging storage time at the time of turn-off. SOLUTION: At the time of turning off a drive transistor 1, a carrier draw- out circuit 5 draws a carrier from a gate electrode. At that time, the carrier is speedily drawn by making the impedance of the carrier draw-out circuit 5 low. A gate current IgL flowing when the carrier is drawn is detected. When the current becomes under a prescribed value, it is judged to be a sign that the drive transistor 1 completes turn-off. The impedance of the carrier draw-out circuit 5 is raised and carrier drawing speed is delayed. Thus, a turn-off operation is gently completed and transistor is prevented from being erroneously turned on due to the gate voltage fluctuation. The turn-off time does not become long.
