Abstract:
A system for recognizing and swapping polarity for DC powered devices that includes a polarity detection module that is configured to identify polarity of DC power input, and further configured to send an output to a controller based on identification of polarity of the DC power input. The system includes a power switch array that is operatively coupled with the controller, and wherein the controller, based on the output, can set one or more switches of the power switch array for executing polarity switching.
