Accurate detection of ripple components of the direct-current (DC) signals is essential for evaluating DC power quality. In this study. the combination algorithm based on variational mode decomposition (VMD) and Hilbert transform (HT) is applied to detect and analyze the characteristics of the ripple components of the DC disturbance signals.
