Title: A Study and Small-Signal Modeling of a Two-Switch Buck–Boost Converter Considering Parasitic Elements †
Keywords: LM5118 controller, non-inverting two-switch buck–boost converter, transfer functions

Abstract: The paper presents an analytical study and small-signal modeling of a non-inverting two-switch buck–boost converter based on the LM5118 controller, accounting for parasitic elements. The converter dynamics were analyzed using simulations in the PLECS® 5.0.2 environment. Furthermore, the steady-state and dynamic characteristics of the LM5118-based two-switch buck–boost converter were examined using the PSpice for TI® simulator for different input voltages and load conditions. The obtained simulation results show close correspondence with the analytical analysis, confirming the validity of the proposed approach.
