Abstract—This paper analyses a different configuration for the classical Z-Source Inverters (ZSI) which is named as Switched Inductor Z-Source Inverters (SL-ZSI) through simulation results. This configuration uses a unique impedance network that helps in the voltage adjustability. Comparing with the ordinary Z-source inverter, the new configuration provides more voltage inversion ability and enhances the output power quality of the main circuit considerably. The various applications of this configuration include DC-AC, AC-AC, DC-DC and AC-DC power conversions.

Abstract:
The presented paper analyzes the detailed design of a trans Z-source inverter (ZSI) with an input from solar photovoltaic (SPV) system. Increase in SPV uses requires highly efficient SPV enabled inverters under varying weather parameters are in high demand in modern smart grid applications. The SPVtrans ZSI has high conversion efficiency because of the single-stage voltage boost conversion capability. In contradiction, the conventional voltage source inverter (VSI) requires an additional step-up transformer to boost the output voltage of inverter. This reduces the efficiency by increasing the volume of set up and also increase the cost of the system. In the proposed SPV system it provides a better output against VSI. The increase in inverter output voltage is because of shoot through time period present in ZSI. It also reduces the voltage stress and harmonics content as compared to VSI. The proposed model has been validated through MATLAB simulation.

Abstract:
Impedance-source (Z-source) inverters are increasingly adopted in practice, where a high voltage gain is required. However, issues like drawing a non-continuous current from the DC source and ceasing the energy supply under DC source faults are also observed. In this paper, an embedded enhanced-boost Z-source inverter (EEB-ZSI) is thus proposed to tackle the issues. The proposed EEB-ZSI employs two DC sources, which enable the continuous input current and fault-tolerant operations (e.g., open-circuit and short-circuit faults in the DC sources). The operational principles are presented in detail with an in-depth circuit analysis. Moreover, the proposed EEB-ZSI is benchmarked with prior-art Z-source inverters. Experimental tests further demonstrate the effectiveness of EEB-ZSI regarding the continuous input current and flexible fault tolerance.

Abstract:
Nowadays, more and more distributed generations and renewable energy sources, such as wind, solar and tidal power, are connected to the public grid by the means of power inverters. They often form microgrids before being connected to the public grid. Due to the availability of high current power electronic devices, it is inevitable to use several inverters in parallel for high-power and/or low-cost applications. So, inverters should be connected in parallel to provide system redundancy and high reliability, which are important for critical customers. In this paper, the modeling, designing and stability analysis of parallel-connected three-phase inverters are derived for application in renewable energy systems. To enlarge voltage adjustability, the proposed inverter employs an improved switched inductor Z-source impedance network to couple the main circuit and the power source. Compared with the classical Z-source inverter (ZSI) and switched inductor Z-source inverter (SL-ZSI), the proposed inverter significantly increases the voltage boost inversion ability and also can increase the power capacity and the reliability of inverter systems. The proposed topology and its performances are validated using simulation results which are obtained in Matlab/Simulink.

Abstract:
Recent research has been focussed on renewable energy due to the rising need for electrical energy. Renewable energy has a low environmental impact compared to other energy sources. As a result, renewable energy sources (RESs) are the best option for generating electricity. Solar photovoltaic is one of the largest renewable power generators. Solar photovoltaic (PV) is connected to the load via power electronic converters. Most PV installations need a two-stage conversion process consisting of a boost converter to increase the load voltage and an AC-to-DC voltage source inverter to power the load. The Z-source inverter (ZSI) can confront the shortcomings of VSI and two-stage conversions. ZSI connects the PV system to the load and is used to increase the system’s performance. This paper discusses the performance of various topologies of ZSI, such as traditional Z-source inverters (XZSIs); for integrating a PV source into a load, switched inductor Z-source inverters (SIZSIs) and transient Z-source inverters (TZSIs) are used. Also, artificial neural networks (ANNs), fuzzy logic controller (FLC), and adaptive neuro-fuzzy inference system (ANFIS)-based MPPT techniques are discussed for obtaining maximum power from PV panels. Based on the maximum power, the shoot-through duty ratio has been adjusted.

Abstract:
AbstractSingle-stage energy converters, in particular, the Z-Source Inverter (ZSI) or impedance source inverter, has gained significant attention in the recent years. ZSI ensures flexible energy conversions (dc–dc, dc–ac, ac–ac and ac–dc) because of its unique ability to boost the output voltage in typical renewable energy systems. The impedance network integrated between the energy source and the load contributes to the unique functionality of the ZSI. As substantial research has been conducted on the ZSI, this article provides a review on the operation of ZSI. The article initially examines the various topologies commonly adopted for the application of the ZSI. Subsequently, details of the various modulation methods that are commonly used to obtain the voltage boosting using ZSI are documented. Additionally, the phenomenon of neutral point formation, which is an important impediment to the adoption of multilevel ZSIs and the limitation of the modulation methods, is explained.

Abstract:
O uso crescente de fontes alternativas de energia exige conversores de energia capazes de aumentar sua tensão nos terminais e conectá-los ao sistema de distribuição. Neste contexto, o conversor step-up clássico (conversor de potência CC/CC) e o inversor de fonte de tensão (VSI) são as soluções mais aplicadas para processar o fluxo de energia da fonte para a rede. No entanto, apresentam um baixo rendimento devido ao duplo estágio de conversão, isto é, a energia flui também através dos conversores de energia CC/CC e CC/CA. Para evitar esse tipo de desvantagem, no início da última década, o Z-Source-Inverter (ZSI) foi introduzido. Nesta nova solução, o conversor de energia CC/CC responsável por elevar a tensão nos terminais do conversor foi removido e uma rede de impedância LCLC foi adicionada com duas tarefas, ou seja, aumentar a tensão do terminal e melhorar a eficiência do ZSI. Infelizmente, os trabalhos da literatura não apresentaram um modelo matemático generalizado para apoiar os projetistas de conversores de potência na análise de estabilidade, projeto de controladores ou avaliar o ganho de tensão do conversor. Neste sentido, esta dissertação propõe o desenvolvimento de um modelo matemático completo e a análise de estabilidade da planta. Para suportar todo o desenvolvimento teórico, foi realizado um conjunto de análises no domínio do tempo e da frequência. Por fim, verificou-se o controle da tensão do elo CC para suportar todas as afirmações apresentadas neste trabalho (controle da tensão no capacitor da rede Z).<br>The growing use of alternative energy sources require power converters able to boost their terminal voltage and connect them to the distribution system. In this context, the classical step-up converter (DC/DC power converter) and the voltage source inverter (VSI) are the most applied solutions to process the power flow from the source to the grid. However, they present a low efficient because of the double stage of conversion, i.e. the power flows through the DC/DC and DC/AC power converters as well. To avoid this type of drawback, in the beginning of the last decade the impedance source inverter (ZSI) was introduce. In this new solution, the DC/DC power converter responsible for boosting the voltage at the DC-source terminals was removed and a Z (LCLC-network) was added with two tasks, i.e. boost the DC-source terminal voltage and improve the ZSI efficiency. Unfortunately, the papers in the literature did not present a generalized mathematical model to support designers of power converters in the analysis of stability, design of controllers or evaluate the voltage gain of the converter. In this sense, this thesis proposes the development of a complete mathematical model and the stability analysis of the plant. To support all the theoretical development a set of analysis in the time and frequency-domain was performed. Finally, the control of DC-link voltage was verified to support all the statements presented in this thesis (control on the Z-network voltage capacitance).

Line after line This project designs and develops novel Z-source inverter and pseudo Z-source inverter architectures and their solar photovoltaic power system upgrades. Computer modeling and in-person testing verify designs' functioning. After studying Z-source inverter topologies, recommended configurations are created. This allows Z-source inverters to handle many applications. Solar PV modules are input sources for Z-source inverter impedance network design. This strategy will be used throughout design. Because of this, solar photovoltaic systems are modeled, simulated, and tested to determine performance. Photovoltaic (PV) modules in various array topologies are tested in normal or partially shaded conditions. Full or partial sunshine works. Simulation produces current-voltage characteristic curves and power-voltage characteristic curves for modules under various temperature and insolation conditions. These curves assess module performance. An experimental scenario is used to determine the optimal solar array design for the proposed Z-source inverter architecture. ZSI solves the AC voltage output-DC voltage intake dilemma. Z-source inverter topologies feature better output voltage gain, smoother frequency, and the capacity to adapt technological upgrades. These benefits have convinced academics that Z-source inverter topologies can reach their potential. Hence, some Z-source inverter combinations have great promise.

Abstract:
Extensive study over Z-source inverter (ZSI) has been pursued for years to compensate the drawbacks of the conventional converters. Single stage (one-step) conversion with buck-boost characteristics was the primary features for its wide usage. But presence of passive elements may prove to be a disadvantage as the size of the converter increases along with its ratings. Modifications on such converters leading to different topologies have been discussed briefly in this paper. The comparative study based on reduced passive elements and better gain is done to obtain an optimal converter structure.

Abstract:
Permanent Magnet Synchronous Motors (PMSM), which operate at extremely high speeds, are frequently used in a broad range of industrial applications today that demand high levels of precision and efficiency, including robots numerical control machines and broad speed range and high efficiency. The performance of a photovoltaic (PV) panel is enhanced by the employment of a improved Z-Source Converter (ZSC) driving mechanism for PMSM in this work.When the PMSM has to function at a fast speed, the ZSC offers a programmable boost voltage. Utilizing Space Vector Pulse Width Modulation (SVPWM) control methods, the PMSM drive's speed is managed. The SVPWM Technique is one of the essential PWM methods for regulating PMSM using a three-phase voltage source inverter (VSI). The PMSM is driven by analysis and simulation using Matlab-Simulink. The PMSM's speed at 2000 and 2500 RPM remains steady after 0.35 and 0.45 seconds, respectively.

Abstract:
Power quality issues are a major concern in modern electrical grids, particularly with the increasing integration of renewable energy sources and sensitive electronic equipment. Dynamic Voltage Restorers (DVR) have emerged as a potent solution for mitigating voltage sags, swells, and interruptions. This paper introduces a novel approach to enhance power quality using a Z-source inverter (ZSI) based DVR, employing Space Vector Pulse Width Modulation (SVPWM) techniques. The ZSI offers unique advantages in this application, including the ability to boost voltage without the need for additional DC-DC converters and the capability to operate under various load conditions. We present a comprehensive design and simulation of the SVPWM Z-source inverter, detailing its configuration, control strategy, and integration within a DVR system. Simulation results demonstrate that the proposed DVR configuration effectively compensates for voltage disturbances, thereby stabilizing the load voltage and improving the overall system performance. Comparative analyses highlight the superiority of the Z-source inverter over traditional inverter designs, showing significant improvements in efficiency and reliability. This study confirms that SVPWM Z-source inverter based DVRs can offer a robust and efficient solution for enhancing power quality in contemporary power systems.

Abstract:
Since the Z-Source Inverter (ZSI) was first proposed in 2003, impedance source inverters (ISI) have experienced a rapid progress. This evolution is not limited to developing network topologies, but also involves their modulation and control techniques to improve their performance and efficiency from different aspects. Accordingly, discontinuous PWM (DZPWM) techniques gained substantial attension in the last few years due to their advantages compared with continuous modulation schemes. The aim of this paper is to study, analyse, and compare three recent DZPWM methods for the Zsource/ quasi-Z-source inverter (qZSI). The operating principal of each DZPWM technique has been presented and analyzed. Moreover, a comparative investigation based on the inductor current ripple, voltage gain, power loss, and some other factors has been carried-out. Finally, computer simulations using MATLAB/Simulink and PLECS softwares have been performed to evaluate the presented DZPWM techniques. Such a comparative analysis helps researchers and designers to choose for their ISI modulation strategy for their application.
