  • Process and circuit for controlling the base drive of a power transistor
    Patent number: 4563596
    Abstract: The derivative of the collector-emitter potential of a transistor (T) relative to the base current is detected preferably by effecting a linear sweep of the base current, the value of this derivative is compared in a comparator stage (5) with a lower limit value and an upper limit value determining an optimum operation zone of the transistor in the vicinity of its quasi-saturation, and the base current is controlled by the result of the comparison. A high gain and an optimum operation of the power transistor (T) are achieved.
