Current limiting circuit arrangements

摘要

Currents greater than predetermined amount are prevented within a circuit arrangement by connecting the electrical supply to at least one conductor via a diode and a transistor, with the diode and the base-collector junction of the transistor in series between the conductor and the supply, and with the emitter connected via a resistor to a point maintained at an appropriate reference potential level, the transistor being in a grounded-base configuration, with the maximum possible collector current defined by the maximum possible emitter current.
