Abstract:
Many inverters play an important role in transmitting and processing energy to power system networks. To reduce the cost and size of multilevel inverters, various topologies have been included in the literature. But these topologies do not look at the complete harmonic distortion in the output waveform. In this study, a modern multilevel inverter structure, a mutated H-bridge inverter is adopted that demands a small amount of switches, driver circuits, power diodes and DC voltage sources compared to conventional multilevel inverters to produce the required level in the output voltage. The mutated H-bridge converter uses a nearest-level control method, produces high value of total harmonic at the output voltage and low-level harmonics content is also high, which is more dangerous than high-order harmonics. Therefore, the selective harmonic elimination (SHE) method is used to reduce the low frequency harmonics and the total harmonic distortion to the output voltage. Comparison of complete harmonic deviation and low-level harmonic content using the above-mentioned control strategies on the 31-level inverter is presented. Simulation studies confirm the performance of a 31-level inverter with low-order harmonics and a complete harmonic distortion using the SHE process. The effectiveness and accuracy of the SHE in producing 31 level waveform is demonstrated by utilizing the test outcomes and the THD found is of the order of 2.8%, 1.7%, 1.7% and 1% for the modulation index values of 0.5590, 0.7440, and 0.8380 and 0.9110 respectively.

Abstract:
The need of higher powers in electrical drives has forced the researchers to develop new power source possibilities. Multilevel inverters have been presented as a cost effective solution for various high voltage and high power applications including power quality and motor drive problems. The traditional pulse width modulated (PWM) Inverter does not completely eliminate the unwanted harmonics in the output waveform. Using the multilevel inverter as an alternative to traditional PWM inverters for electric motor drive applications is investigated. The concept of the Optimized Harmonic Elimination Stepped-Waveform (OHESW) technique for a multilevel inverter is presented. The effectiveness of this technique in minimizing the inverter switching losses and its output voltage harmonic content which cause reducing harmonic losses and torque pulsations of an induction motor fed form is investigated analytically. Comparison between the Selective Harmonic Eliminated PWM (SHEPWM) as a traditional PWM technique for three-level inverter and the OHESW technique for multilevel inverter with regard to the switching losses, harmonic distortion, additional harmonic losses in the motor and the pulsating torques is also presented.

Abstract:
Renewable energy are usually connected to the power grid through an inverter. As the penetration level of such inverter-based distribution generation resources increases, PCC point harmonics become an important concern for grid stability and power quality. In this paper, the PCC-point harmonics in a parallel-inverter-based photovoltaic station were measured and some significant characteristics of such harmonics were presented. These harmonics are stationary; the voltage and current waveforms are lower frequency, power correlation and inter-harmonic. And these harmonics are 3-phase symmetric and contain 3rd and 6th harmonic components. The transitions of the PCC harmonic occurrence and vanishing are instantaneous. The analysis indicates that the PCC harmonics are not produced by the resonances related to the linearities of PV inverters but the inverter nonlinearities are the primary reasons. The strategy to eliminate the PCC point harmonics are proposed in this study.

Penetration of renewable energy in distribution generation increases power quality in the output. The harmonics inherent in the inverters are a major contributor to the power quality issues in the distribution system.

Abstract:
The inverter’s output impedance can be adjusted to reduce harmonic interference on the grid. Advanced current control strategies like PI and quasi-PR control enable precise control of the inverter’s output current, further reducing harmonics. PI control compensates for error signals to eliminate steady-state errors but has limited ability to suppress harmonics in high-frequency ranges. Quasi-PR control combines proportional, integral, and resonance control to suppress specific frequency harmonics. Establishing a grid-connected photovoltaic inverter and harmonic source model is crucial for grid harmonics management. This model provides insights into harmonic generation by inverters, enabling targeted mitigation measures. It can also assess the impact of control strategies on harmonic suppression, providing a theoretical basis for optimization. Optimizing grid inverter control strategies is critical for maintaining grid stability and enhancing power quality. Thorough research on grid-connected photovoltaic inverter harmonics and effective control strategies contribute to renewable energy development and green, low-carbon energy systems.

Abstract— This paper discusses multilevel single-phase inverters to improve voltage quality by reducing harmonics. In order to see the performance of multilevel single-phase inverters in reducing the output voltage harmonics, a comparison of several single-phase multilevel inverters with a multilevel H-bridge topology is performed. Increasing the voltage level on the multilevel inverter will reduce harmonics such that losses will be significantly reduced. Multilevel single phase inverter simulation is performed for three-level, five-level and seven-level inverters using matlab/simulink software. The simulation results show that the Total Harmonic Distortion (THD) output voltage of five levels single phase inverter is smaller than three-level inverter and THD output voltage of the seven levels inverter is smaller than using a five-level single phase and three-level inverter, where the THD can be reduced to 13 45%. Index Terms— multilevel single phase inverter, harmonics, THD.  Abstrak–- Tulisan ini membahas tentang multilevel inverter satu fasa untuk memperbaiki  kualitas tegangan dengan mengurangi harmonisa.  Untuk melihat kinerja multilevel inverter satu fasa dalam mereduksi harmonisa tegangan keluaran dilakukan perbandingan beberapa multilevel inverter satu fasa dengan topologi jembatan-H bertingkat.

Abstract:
This paper presents comparative study of Total Harmonic Distortion (THD) and its individual harmonic contents without grid and with grid for Diode clamped multi level inverter (DCMLI) and Flying capacitor clamped multilevel inverter (FCMLI) based Doubly Fed Induction Generator (DFIG) employing PI and Fuzzy logic controller (FLC). Simple method to control for a variable speed wind energy conversion system with a DFIG is connected to the grid through a diode rectifier and a diode clamped multilevel inverter (DCMLI). The DC-link voltage is controlled through a DC-DC boost converter to keep the DC voltage at constant value. Inverter is controlled by sinusoidal pulse width modulation technique, which supplies power to the grid. The THD and its harmonic content are studied for different wind speeds. DFIG fed flying capacitor multi level inverter (FCMLI) based WECS connected to load as well as grid. FCMLI is controlled through sinusoidal pulse width modulation. Voltage and current harmonics are studied. The results of both multilevel inverters are compared. It shows that the level of harmonic content of two types of multilevel inverters working at different wind speeds indicates that Total Harmonic Distortion (THD) for DCMLI has given best results.

Abstract:
In order to extract the maximum amount of power from the PV modules and convert it into an appropriate form for grid integration, a power electronics interface is needed. This thesis focuses on analysis and modeling of the single-phase two-stage inverter for grid-connected PV application with special attention given to the harmonic issues. A DC/DC battery-integrated boost converter can serve as the front end in a two-stage PV inverter configuration. A steady-state analysis for this new type of converter is carried out. An application of this converter in distributed Maximum Power Point Tracking (MPPT) architecture is proposed and compared with the conventional boost converter. By adding energy storage devices, it has the potential to compensate for the intermittent attribute of the PV generators. It also yields a more stabilized DC-link voltage in the distributed MPPT application. This thesis also analyzes the harmonic distortions generated from a PV inverter, which mainly relate to the DC/AC stage of the PV inverter. The field measurements are carried out at the CSIRO micro-grid. The high total harmonic distortion phenomenon is found when the PV inverters operate at light load condition. The conventional model of a PV inverter does not contain any harmonic information. A linear model for the PV inverter is modified to analyze the harmonic formation process. The causes of harmonics are summarized for the PV inverter operating at different power levels. The constant DC-link voltage assumption is not necessarily true for the two-stage PV inverter. The model of the grid-connected PV inverter with feedback control becomes time-varying with consideration for the DC-link voltage ripple. A series of odd harmonics is identified to be caused by this double-line frequency DC-link voltage ripple. The transfer function cannot be derived for this model. It is a challenge to calculate the exact harmonic amplitudes. The closed-form solution for this time-varying model is derived based on an idea which is similar to the harmonic balance method. A guideline is provided to select the minimum size of capacitor for the DC-link without sacrificing the power quality. Simulation and experimental results are provided to verify the aforementioned analysis results. In addition, some suggestions for future work are given.

Abstract:
This thesis investigates a novel DC/AC resonant inverter of Induction Heating (IH) system presenting a Multilevel Neutral Point Clamped (MNPCI) topology, as a new part of power supply design. The main function of the prototype is to provide a maximum and steady state power transfer from converter to the resonant load tank, by achieving zero current switching (ZCS) with selecting the best design of load tank topology, and utilizing the advantage aspects of both the Voltage Fed Inverter (VFI) and Current Fed Inverter (CFI) kinds, therefore it can considered as a hybrid-inverter (HVCFI) category . The new design benefits from series resonant inverter design through using two bulk voltage source capacitors to feed a constant voltage delivery to the MNPCI inverter with half the DC rail voltage to decrease the switching losses and mitigate the over voltage surge occurred in inverter switches during operation which may cause damage when dealing with high power systems. Besides, the design profits from the resonant load topology of parallel resonant inverter, through using the LLC resonant load tank. The design gives the advantage of having an output current gain value of about Quality Factor (Q) times the inverter current and absorbs the parasitic components. On the contrary, decreasing inverter current means decreasing the switching frequency and thus, decreasing the switching losses of the system. This aspect increases the output power, which increases the heating efficiency. In order for the proposed system to be more reliable and matches the characteristics of IH process , the prototype is modelled with a variable LLC topology instead of fixed load parameters with achieving soft switching mode of ZCS and zero voltage switching (ZVS) at all load conditions and a tiny phase shift angle between output current and voltage, which might be neglected. To achieve the goal of reducing harmonic distortion, a new harmonic control modulation is introduced, by controlling the ON switching time to obtain minimum Total Harmonic Distortion (THD) content accompanied with optimum power for heating energy.

Abstract:
On-line power system (PS) Thévenin equivalent impedance (TEI) estimation involves the reduction of the PS's complex circuit into a simple form that provides valuable insight into its state and behaviour. It finds application in numerous areas such as voltage stability monitoring and islanding detection. In the context of distributed generation (DG), on-line TEI estimation can be easily implemented in existing hardware to add functionality and improve the operation of power converters – the key components of DG systems. Two distinct methods of on-line PS TEI estimation exist. The passive method involves only measurement of voltage and current, whereas the active method involves injection of current into the PS and measurement of the response. This work is focused on the active method. Through a review of the available literature, limitations of past work are highlighted. It is shown that the nature of current injection varies greatly in different works and that evaluation of implementation performance is generally not thorough. Little consideration has been made of the effect of injection current level and frequency on the performance of on-line TEI estimation. Furthermore, the behaviour of the grid and its impact has not been thoroughly investigated. In this work, the active method is implemented in a three-phase PV-inverter and thoroughly tested in terms of its TEI estimation accuracy. Dependence of said accuracy on parameters such as the level of injected current and its frequency is shown to be high through tests performed on the live PS at two locations. These parameters are optimised such that TEI accuracy is maximised and the performance of the device is shown to be good compared to calibration equipment. The accuracy of PS TEI tracking is evaluated and quantified. Considerations are also made of the device's hardware limitations and their effect. A process by which a device's TEI estimation accuracy can be thoroughly evaluated is developed through this work. The behaviour of the PS's TEI is also investigated over long periods and characterised. It is found that the TEI remains steady around an average level in both test locations, with a low standard deviation. Consistency in results is found to be high between the two tests.

Abstract:
Power inverters, used to convert DC power to AC, are often used in e.g. solar power applications. However, they tend to be impractically large and expensive; as such, power miniaturization is an active research area. In this thesis, several classes of modern power inverters are evaluated and compared with regards to size, efficiency and output quality in order to identify areas of potential improvement. Methods for estimation of THD, power losses and input ripple are created and verified against a simulation of a five-level neutral-point-clamped inverter with SPWM control. Finally, this design is implemented physically and is found to achieve 94.5% efficiency and 7% THD under low voltage laboratory conditions, while remaining smaller than an average textbook.

Abstract:
Smart realization involves a steady increase in inverter-based components like Distributed Energy Resources (DER), energy storage systems, and plug-in electric vehicles. The harmonics related to DER inverters and the spread of power electronic devices raises concerns for utilities and customers. Harmonics can create component failures, thermal losses and control system malfunctions. In this paper the authors analyze the impact of multi-source harmonics from DERs inside distribution networks. The harmonics impacts are evaluated by harmonic measurement indices. Harmonic emission in a real distribution circuit is simulated with the help of power flow analysis. The results are presented with visualization techniques to give a better picture of harmonic propagation vs. different levels of harmonic source magnitude and angle. Due to effect of harmonic on network efficiency, a sensitivity analysis considering power factors is conducted.

Abstract:
The demand for higher power quality in industrial applications led to the replacement of two stage inverters with multilevel inverters, which may provide multiple steps of ac output voltage with lower harmonic content. They can thus be utilized in high-voltage and high-power applications. Cascaded H bridge inverters are one of the most used multilevel inverter techniques. Yet as the number of output levels rises, H-bridge inverters use more voltage sources and switching devices, which is one of their main drawbacks. As a result, switching stress and losses rise. In this paper, a modified structure of a switched capacitor multilevel inverter (SCMLI) supplied from a single DC source and requiring fewer switching devices is compared to a conventional cascaded H-bridge inverter. This paper also presents the total harmonic distortion (THD) comparison of 9 levels, 17 levels, and 33 levels of switched capacitor and conventional cascaded H-bridge multilevel inverters. The THD of 9 levels, 17 levels, and 33-level conventional cascaded H-bridge inverters is 14.2, 13.2, and 7.5 respectively. By introducing the modified topology of a switched capacitor multilevel inverter the THD is reduced to 12.57, 9.59, and 4.4 respectively. From the comparison study, the modified SCMLI configuration is considered the most efficient topology with self-balanced voltage capability, a lesser number of switches, and reduced harmonics.

Abstract:
Impedance networks inverters (INI) have emerged as an alternative to improve traditional inverters, allowing their operation as a buck-boost type converter, through the utilization of the "shoot-through" conduction state, where switches of one or more inverter legs are gated on simultaneously. Recently introduced, the Quasi-Y-Source inverter (QYSI) is a magnetic coupled INI that has particular performance advantages, specially for renewable sources and distributed generation. To control the QYSI there is several techniques based on Sinusoidal Pulse Width Modulation (SPWM), that are modified to allow the shootthrough state. This work aims to present, through computational simulations, a comparative analysis of three SPWM techniques applied in three-phase QYSI, considering a fixed boost factor and a three-phase/three-wire RL load connected to the inverter output. The following modulation techniques were compared: Simple Boost Control (SBC), Maximum Boost Control with third harmonic injection (MBC3h) and Maximum Constant Boost Control with third harmonic injection (MCBC3h). Simulation results show operation characteristics of the QYSI for the different modulation techniques. A Fourier analysis was performed in order to evaluate harmonic distortion and harmonic spectrum for both inverter output voltage and current, and a comparative analysis was performed showing several relationships among voltage gain, switch voltage stress, shoot-through duty ratio and modulation index for the different SPWM techniques. Simulation results shows the advantages and disadvantages of each SPWM technique applied to QYSI and the impact of the coupled inductor on inverter performance, helping to establish proper criteria for choosing among SPWM techniques for different power systems applications.
