Dynamic thresholds for power circuit switch operation are calculated in real-time using instantaneous operating parameter measurements. The dynamic thresholds are self-adapting and are used to provide shutdown criteria independent of switch control systems. A characteristics field containing information related to operation parameters is used to make overload evaluations in real-time. These dynamic overload evaluations allow complete protection against thermal overload for entire power circuits in addition to power components. Reserve load capacity can also be determined based on well known component characteristics, which permits the power circuit to be driven at optimal efficiency. The power circuit output profile can also be modified in response to dynamic overload evaluation, thus preventing overload shutdown or damage to components, while operating at optimal efficiency.
