ABSTRACT:
A power system includes a current regulator coupled to a load and for generating an output current having a substantially constant ripple magnitude, and for adjusting the output current according to a sense signal indicative of the output current. In addition, the power system includes a filter element coupled in parallel with the load and for passing an AC (alternating-current) portion of the output current. Furthermore, the power system includes a current sensor coupled between ground and the parallel-coupled filtering element and load, and for providing the sense signal indicative of the output current.
