ABSTRACT:
Certain exemplary 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.
