Asymptotic Stability Analysis of the Limit Cycle of a Cascaded DC-DC Converter Using Sampled Discrete-Time Modeling.

Small LC filters connected to tightly controlled power loads may lead to instabilities. With small LC filters comes a high cutoff frequency, and the conventional stability analysis based on an average model may not be precise enough. Other tools based on another model are required to study this type of system. In this paper, a new discrete-time model is proposed to investigate the behavior of the ...
