Abstract: The large-signal stability analysis of two-stage cascaded dc–dc converter systems is still a troublesome problem due to various limitations of existing stability analysis methods. To address ...

The distance value is defined as the number of elements arr1[i] such that there is not any element arr2[j] where |arr1[i]-arr2[j]| <= d.
