Abstract
A method of suppressing ripple can include: (i) coupling a switching converter and a load in series between output terminals of a signal source; and (ii) controlling a difference voltage between an input voltage signal and an output voltage signal of the switching converter to vary with a voltage signal generated by the signal source to maintain a load current signal flowing through the load as a DC signal.
