Abstract
This article presents an extension of a small-signal discrete-time modeling procedure for dc–dc converters. It considers that the time between samples can be an integer multiple of the switching period of the converter. Then, it can be said that the converter is modeled in undersampling or subsampling conditions. The objective of this article is to obtain a small-signal discrete model, so the degradation in the dynamic performance of the dc–dc converter introduced by the subsampling conditions can be assessed, and a proper controller can be designed.
