Claim 17:
18. A power supply signal conditioning and adaptation system, the system comprising:
a power supply operably coupled to one or more loads, wherein, when enabled, the power supply is configured to output a power supply signal having a DC (direct current) voltage component and a ripple voltage component that is based on conversion of an AC (alternating current) signal in accordance with generating the power supply signal;
a drive-sense circuit (DSC) operably connected via a single line to a coupling between the power supply and the one or more loads, wherein, when enabled, the DSC is configured to:
sense the power supply signal and, based on sensing of the power supply signal, simultaneously adaptively to process the power supply signal including to inject, via the single line to the coupling between the power supply and the one or more loads, a current signal that is based on the sensing of the power supply signal in accordance with reducing or eliminating the ripple voltage component of the power supply signal to generate a conditioned power supply signal to service the one or more loads; and
generate a digital signal that is representative of any non-uniformity of the power supply signal, wherein the DSC includes:

a low pass filter (LPF) configured to process the power supply signal to generate an LPF signal;
a comparator configured to compare the LPF signal to the power supply signal to produce an analog comparator output signal;
an analog to digital converter (ADC) configured to process the analog comparator output signal to generate the digital signal that is representative of any non-uniformity of the power supply signal;
a digital to analog converter (DAC) configured to process the analog comparator output signal to generate another analog comparator output signal; and
a current supply circuit configured adaptively, based on the another analog comparator output signal, to inject the current signal that is based on the sensing of the power supply signal via the single line to the coupling between the power supply and the one or more loads; and
one or more processing modules operably coupled to the DSC and to the power supply, wherein, when enabled, the one or more processing modules configured to:
receive and process the digital signal that is representative of any non-uniformity of the power supply signal; and
generate, based on the digital signal that is representative of any non-uniformity of the power supply signal, a control signal and provide the control signal to the power supply to modify and adapt operation of the power supply in accordance with reducing or eliminating the non-uniformity of the power supply signal.
