Abstract
A current limiting circuit is disclosed which comprises means for monitoring an electrical current to be controlled, means for generating a signal having a periodically variable value, and means for adjusting the periodic signal in accordance with the value of the current to be controlled. A comparator produces a signal having a first value when the value of the periodic signal is below the value of a threshold, to change the duty cycle of its output in the direction which causes comparator-responsive means to decrease the monitored current.
