    The proposed research strategy aims to conduct a comprehensive investigation and optimization of power electronic devices utilized in the context of renewable energy applications, specifically focusing on solar and wind power systems. The primary objectives of this study encompass an in-depth analysis of the performance and efficiency of a diverse range of power electronics components, including converters, inverters, and controllers, with a specific focus on identifying areas with potential for enhancement. To achieve these objectives, advanced simulation software will be leveraged to develop sophisticated models and rigorously assess the operational characteristics of power electronics devices under varying conditions, accounting for parameters such as load fluctuations, temperature variations, and input voltage disparities. Furthermore, this research will intricately delve into the intricate interplay between different power semiconductor materials, device configurations, and control strategies, with the overarching goal of discerning their collective influence on the overall performance and efficiency of power electronics devices. The ultimate aspiration is to distil and propose the most promising design and control strategies capable of effecting substantial improvements in the efficiency and reliability of power electronics devices tailored for application in the realm of renewable energy.
  • Performance Analysis of 250kW Grid-Connected Photovoltaic System
    V Lakshmi Devi, K Kumar, G Vasavi, M Priya, K Murali Kumar
    2024 3rd International Conference on Trends in Electrical Electronics and Computer Engineering Teeccon 2024, 2024
    The utilization of renewable energy sources such as solar and wind power for the creation of electrical energy has become increasingly prevalent in response to the growing demand for electricity. The incorporation of renewable energy sources into the system is crucial for efficient energy consumption. Directly injecting power from renewable energy sources into the grid is a challenging task. Therefore, the system requires power electronic inverters to serve as a connection between renewable energy sources and the grid or load. This research examines the performance of a 250 KW grid connected to a solar system under three different input source scenarios. The inverter generates a clean sinusoidal voltage of 415 V in three phases, which is then used to supply power to the grid and the three-phase load. This study offers several additional benefits, including reduced switching losses, decreased voltage stress of dv/dt on switches, and improved electromagnetic interference. The MATLAB/Simulink software is used to simulate and evaluate the performance of a 250 KW grid. The accuracy of the results will be confirmed.
  • Circulating Current Control of Phase-Shifted Carrier-Based Modular Multilevel Converter Fed by Fuel Cell Employing Fuzzy Logic Control Technique
    Murthy Priya, Pathipooranam Ponnambalam
    Energies, 2022
    The contribution of the modular multilevel converter (MMC) in integrating non-conventional energy sources into the grid is significant; the integration of fuel cells with distributed energy sources is especially prominent as they provide a constant voltage and current for constant load applications. Still, there is a high demand for a high-quality power conditioning unit since there is an occurrence of frequent power spikes. Further, the circulating current (CC) in phase legs is an inherent phenomenon of MMC that must be mitigated. Hence, this article proposed an MMC incorporating a fuzzy logic controller (FLC)-based technique to control the circulating currents. The fuzzy controller effectively reduced the harmonics of the CC in the dc-link system. In addition, phase-shifted carrier (PSC) modulation was employed for the MMC to improve the capacitor voltage balancing to maintain the constant input voltage. Moreover, a mathematical analysis of PSC modulation for MMC was performed to identify the PWM harmonic characteristics of the output voltage and the CC. The performance analysis of the proposed system was tested using the hardware in loop (HIL) simulation with the help of the real-time simulator OP-5700 to verify the feasibility.

    Multi-level converters have gained a reputation in both Medium-Voltage and Low-Voltage applications. To find out the connections among several multilevel Voltage Source Converter (VSC) topologies and to expose in what way to attain innovative topologies. Between them, VSC attained the main market share and taken obvious improvements in the earlier time. The most topical developments in the VSCs is a Modular Multi-level Converter (M-MC). This configuration has a modular structure; power rating and voltage of the converter can be enlarged by accumulating the Sub-Modules (SM) in series. This paper presents the VSC based M-MC of high power converters, which the controller controls the voltage on the load using a PI controller. The simulation results of converter voltage, converter current, grid voltage, grid current, PI error voltage, three-phase instantaneous real power, and reactive power obtained to justify the achievement of the suggested topology.
  • Modular-multilevel converter topologies and applications – A review
    Murthy Priya, Pathipooranam Ponnambalam, Kola Muralikumar
    Iet Power Electronics, 2019
    Recently developed modular-multilevel converter (M-MC) has a major attention in the industry and research works which is moving into feasible technology for many medium and high-power applications. M-MCs have been improved by existing power conversion technology in several aspects, including efficiency, modular structure, power quality, transformerless operational capability, fault tolerant and redundancy operations having a low expense, standard components utilisation, high availability, excellent quality of output wave forms. However, as several challenges combined with M-MC topologies, include reduced voltage stress, compact size, and substantially lower semiconductor losses. These attributes the lower operating cost for high-power applications such as distribution systems and high-voltage direct current (HVDC) transmission systems. The main contribution of this study is to bring the scrutiny of M-MC applications and different circuit topologies. These M-MC configurations consist of converter structures with sub-module converters and M-MC family members. In such a way, the M-MC applications are generalised and it results the size and cost halved, reduced conduction and switching losses and increases system reliabilities. Moreover, in each application of M-MC, drawbacks, and advantages have been discussed in detail. This review presents the latest performance of M-MC with respect to the mentioned research areas and new applications.
