A Universal PSpice Simulation Model of a Switched Buck Voltage Regulator

Abstract

The article describes the design of a universal simulation model of a voltage regulator for applications compatible with the globally used PSpice program. Users can create a model of any type of integrated switching voltage regulator that is currently available on the market by setting its individual parameters. The proposed connection of the regulator was applied in the connection of the buck DC–DC converter. The accuracy of the model was verified by comparing the results obtained by the simulation to other official models and to practical measurements taken on a real sample of the converter. The versatility of the model was proven by comparison with another type of converter with different parameters.

Efficiency Optimization in Multi-Branch Converters through Dynamic Control

“…It should be emphasized that both simulations and experimental results encompass the inclusion of the aforementioned diodes, and thus, the analysis takes these diodes into account. The diode's presence does not invalidate the subsequent analysis proposed herein, nor does it impact the validity of the simulation or experimental findings [19,[21][22][23][24][25][26][27].…”

“…In paper [19], the authors propose an algorithm based on the variable-step conductance increment method and pseudo-MPP correction. This algorithm also enhances the MPP search in response to changes in solar radiation.…”

“…From the studied publications, there is a strong emphasis on achieving the most precise MPP tracking over time. Any improvement in the tracking represents an increase in the efficiency of the converter's operation and enhances the conversion of DC electrical energy to AC [17][18][19].…”

“…The article is structured into multiple sections, each addressing distinct aspects of the study. The first section delves into the mathematical model, where fundamental principles, parameters, and parasitic values of various converter components are employed to derive an equation [19]. This equation determines the optimal number of branches in the converter for a given input voltage and current.…”

“…The fourth section revolves around the design and validation of a control algorithm, which can serve as an extension to existing methodologies. This structured approach allows for a comprehensive exploration of the converter's behavior and efficiency optimization across different facets of the study [19][20][21][22].…”
