Continuous-Control Power Sources That Use Transistors
(AREA)
Abstract
Protective device for voltage regulator circuits, integrated and also for discrete circuits, based on the same operating principle, essentially characterized by the provision of a discrete transistor associated with another transistor in such a way that the effects of the temperature coefficient of the base voltage -emitter of both are compensated, giving a practically zero coefficient, allowing this circuit, applied as a current limiter, the continuous adjustment of the maximum output current within a certain range of values, being fixed by the position of the cursor of a potentiometer and the value of the same is detected by the voltage drop produced in a resistor located in series with the positive output conductor of the power supply.
