Abstract
A system includes a sinc filter module and a cyclic integrator module. The sinc filter module (i) determines a direct current (DC) voltage component of an error between a measured output voltage of a switched-mode power supply and a reference voltage and (ii) determines a signal with ripple by subtracting the determined DC voltage component from the error. The cyclic integrator module (i) applies a learning gain to a difference between the determined signal with ripple and a predicted ripple, (ii) performs integration of each of N segments of the gain-applied difference, and (iii) generates the predicted ripple by reconstructing the N integrated segments, wherein N is an integer greater than one.
