Modeling, Simulation, Analysis, and Design of Linear and, or Nonlinear Electrical Circuits Under Various Operating Conditions

Dear Colleagues,

This Special Issue, titled “Modeling, Simulation, Analysis, and Design of Linear and, or Nonlinear Electrical Circuits Under Various Operating Conditions”, aims to reflect a comprehensive and methodical approach to the study and development of electrical circuits, which are fundamental components in modern electronic and power systems. The inclusion of both linear and nonlinear circuits acknowledges the complexity and diversity of real-world applications, where idealized assumptions are often insufficient. By integrating modeling and simulation, the research included emphasizes the importance of creating accurate mathematical representations and employing computational tools to predict circuit behavior. Furthermore, the analysis phase enables a deeper understanding of performance characteristics and potential limitations, while the design component focuses on optimizing circuit parameters to meet specific functional and operational requirements. Addressing various operating conditions ensures the robustness and adaptability of the circuits, making this topic highly relevant for advancing both theoretical knowledge and practical innovations in electrical engineering.

This Special Issue addresses diverse applications that span multiple domains of electrical and electronic engineering. These include the design and optimization of power converters and amplifiers, the development of control circuits in automation and robotics, signal processing systems, and the modeling of energy-efficient components in renewable energy technologies. Additionally, the methodologies can be applied in embedded systems, automotive electronics, telecommunications, and medical devices, where accurate circuit behavior under varying conditions is critical for safety, performance, and reliability.

Focus

The topics included center on the rigorous and systematic investigation of electrical circuits, encompassing both linear and nonlinear types. The primary focus is on understanding how these circuits behave and perform under a wide range of operating conditions, which may include steady-state, transient, and dynamic regimes. By addressing both types of circuits, this research acknowledges the diversity of real-world electrical systems and the necessity to go beyond idealized linear assumptions.

Purpose

The main objective of this Special Issue is to develop accurate and efficient methodologies for representing and analyzing electrical circuits, ultimately contributing to improved circuit performance, reliability, and functionality. Our purpose is not only to understand how circuits operate under ideal conditions but also to predict their responses to disturbances, parameter variations, and nonlinearity. This approach supports the development of robust design strategies, optimization techniques, and simulation tools that are essential in both academic research and industrial practice.

Scope

The scope of this Special Issue has been made intentionally broad to capture the complexity of modern electrical systems. It includes the mathematical modeling of circuit elements, numerical simulation using specialized software, theoretical and empirical analysis, and iterative design processes. Both passive and active components are considered, and the circuits studied may range from simple analog configurations to complex mixed-signal systems. The investigation spans a variety of operating conditions, such as DC, AC, transient, and switching environments, ensuring that the methods developed are applicable to a wide spectrum of technologies, including power electronics, communication systems, and embedded control circuits.

Relationship to The Existing Literature

This Special Issue builds upon a well-established body of work in circuit theory and electrical engineering but extends it by integrating modern simulation techniques and addressing nonlinear behaviors that are often overlooked in classical analysis. It aligns with contemporary trends in the literature that emphasize the importance of computational tools such as SPICE, MATLAB/Simulink, and other circuit simulators in engineering workflows. Furthermore, it draws on foundational texts in circuit analysis, control systems, and electronic design, while contributing to ongoing debates around model accuracy, simulation fidelity, and system optimization.
