Abstract: A power supply signal conditioning system includes a power supply, one or more loads, and a drive-sense circuit (DSC). The power supply is operably coupled to one or more loads. When enabled, the power supply 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. The DSC is operably coupled to the power supply. When enabled, the DSC is configured simultaneously to sense the power supply signal and, based on sensing of the power supply signal, adaptively to process 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.
