Vol 8, No 3 (2023): Comparison of Conventional Z-Source Inverter and Modified-Z-Source Inverters

Authors: Harish Kumar V C, Shibu Ganesh

Abstract: This paper investigates the performance analysis of the Modified-Z-Source Inverter with a simple voltage boost control method.

Vol 7, No 3 (2022): Investigation and Modeling of the Seven-Levels-Ten Switch Inverter Topology

Authors:- Mahesh Kumar, Santosh Pathak, Vaibhav Nanda

Abstract:- Multilevel inverters outperform typical two-level inverters due to lower harmonic distortion, less electromagnetic interference, lower common mode voltage, and greater dc link voltages. However, the primary disadvantages of multilayer inverters include sophisticated pulse width modulation management, capacitor voltage balancing, and an increased number of switches. The purpose of this work is to investigate and simulate a single phase seven level inverter design utilising just 10 switches. In addition, two distinct control strategies for a seven-level-ten switch inverter architecture are presented in this study. The R- load is connected to the inverter, and simulation is carried out using the MATLAB/Simulink software.

Vol 7, No 3 (2022): BLDCM Drive with Two-Leg Inverter for High-Speed Applications

Authors:- Devesh Singh Kushwah, Kapil Sharma, Abhimanyu Singh

Abstract:- Traditional motor technology is used in small and big scale applications such as car industries, residential appliances such as refrigerators, washing machines, and air conditioning units. These traditional motors have low torque, costly maintenance, and low efficiency. The use of BLDCM improves numerous performance parameters such as better efficiency, higher torque, high power density, minimal maintenance, and lower noise when compared to traditional motors. The biggest disadvantage is the expensive cost. This study proposes a two leg inverter fed BLDCM drive with just four switches and two current sensors, as opposed to six switches and three current sensors in the case of a three leg inverter fed BLDCM drive. The use of fewer switches and current sensors results in reduced switching loss and lower costs. A two-leg inverter-fed BLDCM drive with two input DC sources is suggested in this study. In MATLAB / SIMULINK, the suggested PMBLDCM drive is modelled and its performance is simulated. This suggested technique is simple, cheap cost, and results in improved diving performance, such as decreased torque ripple, less voltage stress, low current THD, and quick dynamic performance of the PMBLDCM drive.

Vol 7, No 3 (2022): A Review on New 7-Level H-Bridge Inverter-Fed Induction Motor with Low Harmonics

Authors:- Rakesh Singh Kumwat, Jayant Kumar

Abstract:- A multilevel structure with more than five layers has the potential to drastically diminish harmonic content. The number of levels increases the output voltage and power. Adding a voltage level necessitates the addition of a primary switching device to each phase. The objective here is to create the seven-level H-Bridge inverter with the fewest switches possible. This circuit's output is delivered to the induction motor. Using this approach, we can adjust the speed of the induction motor while also reducing noise and vibration. This study focuses on increasing the efficiency of multilayer inverters and the quality of the output voltage waveform. With only seven switches, a new seven-level strategy is implemented. The MATLAB simulation has been completed, and the hardware has been constructed by using IGBTs for the seven switches of the seven-level inverter.

Vol 7, No 3 (2022): Integrating Voltage Source Converters (VSCs) into Weak Grids with a Power Damping Controller that Features Self-Synchron

Authors:- Gourav Bhatnagar, Ajit Chattopadhyay, Pravat Biswa

Abstract:- In this study, a novel control topology based on the BATS Echolocation Algorithm is utilised to enable successful integration of voltage source converters (VSCs) in weak grids. A linear power-damping and synchronising controller, consisting of two major sections, automatically synchronises a VSC to a grid by supplying damping and synchronising power components, and enables effective full power injection even under very weak grid circumstances. For frequency and angle regulation, the controller employs cascaded angle, frequency, and power loops. The controller simulates the dynamic behaviour of synchronous machines, making grid integration easier and providing a virtual inertia control framework for VSCs to dampen power and frequency oscillations. While the linear controller provides stable and smooth operation in many circumstances, it cannot guarantee system stability in weak grids when big unexpected shocks quickly shift system dynamics to the nonlinear zone. To overcome this complexity, the BATS Echolocation Algorithm-based controller was created to assist the linear controller and improve system performance in the face of large-signal nonlinear disturbances such as self-synchronization, disturbances in grid frequency and angle, high power injection in very weak grids, and fault-ride-through conditions.

Vol 7, No 3 (2022): Improving Power System Stability using Matlab and Space-Vector-Modulation-Based Statcom

Authors:- Kavita Sharma, Ritu Maheshwari

Abstract:- This study shows how to create power flow sharing in a power system utilising programmable AC sources that feed linear and nonlinear loads. SVPWM is a control technique used in a three-phase Voltage Source Converter (VSC) that serves as a Static Synchronous Compensator (STATCOM) to provide reactive power compensation. In addition to reactive power correction, a Voltage Source Converter utilised as a Static Synchronous Compensator provides effective damping for subsynchronous resonance, which improves the stability of renewable hybrid power systems [2]. The Voltage Source Converter with space vector control method is offered for correcting reactive power flow in order to rectify power factor, eliminate harmonics, and balance both linear and non-linear loads. Among the many PWM strategies, the space vector technique is recommended because it is simple to increase digital realisation and AC bus use. The suggested control technique is based on an approximation of the Voltage Source Converter's third-order nonlinear model, which compensates for uncertainty in three phase system parameters. The use of a Space Vector Pulse Width Modulation controller is recommended as a control approach for dependable power sharing between AC power sources in the grid and loads.

Vol 7, No 2 (2022): Partial Discharge, Detection Mechanism, Rogowski Coil

Authors:- Sushil N. Raja, Puneet D. Khanderao

Abstract:- Electrical discharge machining, also known as spark erosion machining, is a type of machining that falls under the category of thermal machining. It is primarily used as a method for the production of a wide variety of constantly shifting geometries and is frequently carried out as a unit job or in small batches. The fundamental idea behind the Electrical Discharge Machining (EDM) process is to create out of metals that have been altered by the abrupt halting of the electron beam [3] by the solid metal surfaces of the anode. This is the primary function of the procedure. The temperature approaches the boiling point in the section of the anode that is exposed to the direct electrical pulse. Even in the event of a medium-long pulse, the rate of temperature increase is still in the tens of millions of degrees per second range, which indicates that an explosive process is being dealt with. In this study, a combined optimization strategy is utilised to estimate the maximum metal removal rate (MRR), the lowest tool wear rate (TWR), the surface roughness (SR), and the overcut (OC) produced by electrical discharge machining (EDM). [5] Considered here are the critical input parameters voltage (V), pulse on time (Ton), pulse off time (Toff), and current (I).
