Simplified Small‐Signal Modeling Method for Non‐Isolated High Step‐Up Converters

International Journal of Circuit Theory and Applications, Volume 54, Issue 10, Page 4859-4875, October 2026.
A generalized small‐signal modeling methodology for a family of non‐isolated high step‐up DC‐DC converters is proposed. ABSTRACT This work presents a generalized small‐signal modeling methodology for a family of DC–DC converters based on the four‐state switching cell with a wide conversion range (WCR‐4SSC) operating in continuous conduction mode (CCM).
