Sliding mode control (SMC) of induction motor is a new concept in the current scenario, as it seeks to improve torque control accuracy and power steering efficiency through the use of pulse width modulation schemes. Furthermore, artificial neural network‐based sliding mode control is applied to a squirrel cage induction motor, which is used in the steering control of automobiles. The artificial neural network (ANN)‐based SMC is more popular due to its robustness and good stability in external parameter variation. Additionally, an SMC and an ANN‐based SMC are employed to compute the torque and flux, improving performance for power steering applications. The performance of the designed model is validated through MATLAB/Simulink and experimental models with different controllers under various operating conditions. The controller has been embedded into a TMS320F28335 controller, and performances have been evaluated. The performance analyses of induction motor using different controllers are performed. The transient performances of induction motor such as delay time, rise time, settling time, and steady‐state error are investigated. The proposed work is analysed by using a mathematical model and implemented in a test‐bench model for validation.

This paper proposes a step-up 3-Ф switched-capacitor multilevel inverter topology with minimal switch count and voltage stresses. The proposed topology is designed to provide five distinct output voltage levels from a single isolated dc source, making it suitable for medium and low-voltage applications. Each leg of the proposed topology contains four switches, one power diode, and a capacitor. The switching signals are also generated using a staircase universal modulation method. As a result, the proposed topology will operate at both low and high switching frequencies. To highlight the proposed topology’s advantages, a comparison of three-phase topologies wasperformed in terms of the switching components, voltage stress, component count per level factor, and cost function withthe recent literature. The topology achieved an efficiency of about 96.7% with dynamic loading, and 75% of the switches experienced half of the peak output voltage (V_DC), whereas the remaining switches experienced peak output voltage (2V_DC) as voltage stress. The MATLAB/Simulink environment was used to simulate the proposed topology, and a laboratory prototype was also built to verify the inverter’s theoretical justifications and real-time performance.

Multilevel inverters are becoming more popular in the power conversion systems for high power and power quality demanding applications. The MATLAB based simulation on SIMULINK platform is presented for the Single Phase five level cascaded H-bridge Multilevel Inverter (CHB-MLI) topology with less number of switches and with different control schemes and Sinusoidal Pulse Width Modulation (SPWM) schemes. A detailed comparison of various control schemes is presented in this paper with reference to Total Harmonic Distortion (THD) in the output voltage and utilization factor of the power devices. It is observed that among all the control schemes, the THD is minimum in the Sinusoidal Pulse Width Modulation-Phase Disposition (SPWM-PD) scheme with variable carrier wave magnitude

This paper presents a new single-source switched capacitor- (SC-) based multilevel inverter (MLI) design with a boosting potential of three times the supply voltage. To produce a waveform with seven output voltage levels, the suggested switching capacitor inverter consists of eight switches, single diode, and two capacitors. Because capacitors are inherently balanced, there is no need for a balancing circuit or sensor. The structure can be expanded using the provided generalized equations. In addition, the technique for switching control and loss analyses is explored. A fair comparison with the most recent SCMLI topologies has been conducted to demonstrate the merits of the proposed work. Furthermore, the proposed topology is evaluated using the MATLAB/SIMULINK tool, and experiments under both transient and steady-state situations are performed to demonstrate its feasibility. At dynamic-loaded situations, the performance of the proposed SCMLI with dynamic modulation index and switching frequency is tested.

The switched reluctance motor (SRM) has more salient features such as high starting torque, isolation of phase windings, and no rotor windings. Similarly, a permanent magnet brushless direct current (BLDC) motor possesses numerous merits such as high power density, and low torque ripple. However, this SRM and permanent magnet BLDC motor suffer from torque ripple and cogging torque, respectively. Therefore, this research article enriches the design procedure and characteristics of a 3-kW, 60-V hybrid reluctance motor with minimum torque ripple and vibration. Furthermore, this proposed motor is modeled and analyzed with various laminating core materials such as 47F165, Arnon 7, M420-50D, M300-35A, 36F155, and M-27 24Ga for identifying the superior material by considering the relevant parameters such as losses and torque. In the proposed doubly salient motor, a vibration analysis is also performed to predict its natural frequency. A laboratory arrangement is implemented to examine the proposed motor at no-load conditions. Then no-load current and vibration frequency were measured by a digital storage oscilloscope and accelerometer, respectively. These experimental outcomes are compared with finite-element analysis and analytical equations to validate findings.
