ABSTRACT:
Power distribution apparatus, for controlling supply of a current from an electrical power source to at least one load, includes a current sensor, which is coupled to provide an indication of a magnitude of the current flowing to the at least one load. A current limiter is adapted, responsive to the indication, to apply a pulse width modulation to the current drawn from the source so as to maintain the magnitude of the current flowing to the at least one load within a predetermined limit.
