More Information
Summary:The device for controlling the switching of a transistor (1) comprises: - said transistor (1) including a control electrode (4) and power electrodes (5, 6); - a control circuit (7) connected to the control electrode (4); and - means (2, 3, 8) for limiting a time derivative of a power current (i(t)) flowing between the power electrodes (5, 6). In accordance with the invention, the limiting means (2, 3, 8) servocontrol a measurement voltage (V L2) proportional to the time derivative at a predetermined reference voltage by applying an error voltage to the control electrode (4).
