DYNAMICALLY ADAPTING DEVICE OPERATIONS TO HANDLE CHANGES IN POWER QUALITY

A system is described that includes a power bus, a power source configured to supply power to the power bus, and a device receiving at least some of the power supplied by the power source. The device is configured to determine a quality level of the power received from the power bus, and perform an operation of the device according to the quality level of the power. The quality level of the power may be determined on an output from a wavelet transform. For example, the device may apply a wavelet transform to a function based on the power, isolate disturbances from the output of the wavelet transform, and based on the disturbances, determine the quality level of the power.
