Ltspice Based Stability Analysis of Boost Synchronous Dc-Dc Converter

This report presents a stability analysis of a synchronous boost DC-DC converter, performed using LTSpice - a software platform for simulation of analog electronic circuits. The purpose of the study is to evaluate the behavior and stability of the converter in different operating modes, by analyzing the frequency response of the feedback. The amplitude and phase margins, which serve as the main indicators of the stability of the system, were calculated using $A C$ analysis. The report examines the influence of the regulator parameters, filtering components and load conditions on the dynamic response of the circuit. The presented simulation results demonstrate the importance of precise design of the regulator loop and confirm the effectiveness of LTSpice as a tool for preliminary verification and optimization of power systems. A major advantage of using LTSpice is the ability to implement an additional way to analyze the power circuit of a synchronous buck converter. The analysis supports a better understanding of the principles of stable operation of DC-DC converters, which is essential for the modern electronics and could reduce losses in the circuit.
