Abstract: Certain example embodiments disclosed herein include an adaptive current limiter comprising a variable reference voltage generator which is coupled to a power source via two input nodes and which develops a voltage step with exponential decay in response to, for example, a transient over-voltage condition, with the output of the variable reference voltage generator supplying a reference voltage to a comparator which compares the reference voltage to a voltage derived from a sensing resistor and, upon detecting an over-voltage condition, signals to a circuit breaker that the circuit should be broken or modified.

Abstract: An adaptive current limiter is coupled to a power source and which comprises a variable reference voltage generator which provides a variable reference voltage which is inversely proportional to the input voltage from the power source, which in certain embodiments is representative of the maximum allowable current level that may flow through a connected load at the present voltage provided by the power source given a fixed power limit. The current flow to the load is interrupted when the power level provided to the load exceeds predefined constant power and/or constant current limits.
