A Comparative Analysis of Transient Analysis Results for DC-DC Regulator in PSpice, Tina, and LTspice

The paper presents a comparative analysis of the simulation results of a DC-DC buck regulator based on LM2595 on three different simulation platforms: PSpice, LTspice, and Tina. The comparative analysis includes visual comparison of selected waveforms, comparison of statistical parameters of the observed signals, and comparison based on time step signal analysis. The simulation was performed using three different maximal time step conditions. The research focused on examining the differences caused by different simulation platforms under the same maximal time step condition, as well as the differences caused by different maximal time step conditions within a single simulation platform. This analysis is crucial, particularly when comparing different simulation Spice models that require simulations to be conducted on various simulation platforms. By comparing the results obtained from different platforms under the same simulation conditions, the impact of the simulation platform on the accuracy and behavior of the models can be assessed.
