“…In this case, there is a vertical shift of the triangular waves, and their peak to peak amplitude -including the frequency -is the same. There are mainly three types of strategies and they can be represented as: 1) in phase disposition (IPD) [72], 2) phase opposition disposition (POD) [72] and 3) alternate phase opposition disposition (APOD) [72] PWM technique.…”

A multilevel inverter is implemented for generating the required staircase AC voltage of output from various steps of voltages of DC sources. The multilevel inverter gives a better harmonic spectrum and a compatible quality of output. This article delves into an analytical analysis of the total harmonic distortion (THD) of different multilevel inverters which employ a multicarrier PWM technique. This technique is implemented for operating the switches at their respective angle of conduction. This paper deals with various cascaded H-Bridge multilevel inverters (CMI) with various loads that are modelled by implementing the MATLAB/Simulink platform. The output gives a better result of the proposed model in terms that it is helpful towards reducing the THD and the losses of switching.

Micro grid systems have emerged as a promising solution for integrating renewable energy sources and enhancing the overall reliability and efficiency of power distribution. The design and stability analysis of converter topologies play a crucial role in ensuring the seamless operation of micro grids. This research focuses on the development and optimization of converter topologies through advanced control techniques to enhance the stability and performance of micro grid systems. Special attention is given to the challenges associated with the integration of renewable energy sources, such as variable output and intermittent nature. A novel converter topology is proposed to address these challenges, leveraging advanced power electronics and control methodologies. The stability analysis is conducted using optimal control techniques to ensure robust and reliable operation of the micro grid. Mathematical models and simulation tools are employed to assess the dynamic behavior of the proposed converter topology under various operating change in load conditions. The research explores the potential of micro grid system with the converter topology to enhance the micro grid's overall stability and response to load variations. The results of the stability analysis highlight the improvements achieved in terms of system response, efficiency, and reliability.

“…The trigger angle of the inverter switch gate requires precise considerations and calculations so that a small THD index can be obtained. There are various kinds of control for inverters, one of the simplest control methods is sinusoidal pulse width modulation (SPWM) [18], [19]. The SPWM-based method is the right way to reduce THD in a multilevel inverter gate switch because it has a better dynamic response and small commutation load with reduced switching losses [20] .Some other applications of this inverter are to control the speed regulation of induction motors [21] and as an intermediary in the power grid between renewable electrical energy (PV) generators and power plants [22].…”

This DC-to-AC voltage converter is designed for output frequency controlled by a 9-level cascade H-bridge cyclo inverter with pulse width adjustment. The aim of the study was to determine the pattern and format of the voltage, output frequency, and Total Harmonic Distortion index of a 9-level IGBT cyclo inverter. The method used is to build a unidirectional power converter design modeling into 9 alternating levels with cyclo converter-controlled frequency settings using the Simulink MATLAB tool. The cyclo converter section is constructed with two P and N converters in a parallel arrangement. The frequency and trigger pulse width of both converters control the output voltage and frequency format of the cyclo inverter. The test results show a series of ladder waves with an output frequency, of (1/2f, 1/3f, 1/4f, 1/5f, 1/6f, 1/7f, 1/8f, 1/9f, and 1/10f). The simulation results show that the nth input frequency divider waveform is characterized by the emergence of a number of step pulses of n positive half cycles and negative half cycles. The Total Harmonic Distortion Index gets bigger when the system circuit is designed at a low frequency. This modeling can be implemented into a prototype that is used for variable-speed DC motor drivers.
