Abstract: A power converter is provided that includes a detection circuit configured to determine a power source type based on at least one characteristic of power received from a power source. The detection circuit is also configured to determine an operating edge of the soft AC source by monitoring at least one parameter as the soft AC power source approaches a power limit, and assign an operating point to the soft AC power source based on the operating edge to increase power delivery of the soft AC power source.

Abstract: A power distribution busway joint monitoring sensor assembly is provided. A first sensor is configured to measure a first position temperature and generate a first signal indicative of the first position temperature, wherein the first position is proximate to a busway joint. A second sensor is configured to measure a second position temperature and generate a second signal indicative of the second position temperature. A sensor controller is configured to i) receive the first signal and the second signal, ii) process the first signal and the second signal, and iii) generate a processed first signal and a processed second signal. A system controller is configured to receive the processed first signal and the processed second signal and generate an alert when a temperature differential between the first position temperature and the second position temperature is greater than a predetermined threshold temperature.
