The multilevel inverter (MLI) has been developed as a powerful power conversion scheme for several processes, including renewable energy, transmission systems, and electric drives. It has become popular across medium- to high-power operations due to its many advantages, including minimum harmonic content, low switching losses, and reduced electromagnetic interference (EMI). In this paper, the capacitor voltage balancing technique-based pulse width modulation (PWM) has been proposed. The proposed PWM strategy offers several advantages, such as high-quality output waveforms with reduced harmonic distortion, improved efficiency, and better control over the output voltage. The Xilinx ISE 10.1 software was used for synthesizing, and the VHDL code was written for the proposed method. MATLAB software was used to simulate and hardware was used to verify the proposed system. The SPARTAN 3E FPGA was used for the generation of the PWM. This paper developed a 2 kW single-phase 15-level inverter that created an AC wave from the DC input voltage, with a total harmonic distortion (THD) of 8.02%, which was less than the THD achieved from other conventional MLI. The results indicate that MLI topologies with low total harmonic currents, fewer switches, and higher output voltage levels are better stabilized during load disturbance circumstances.

Summary The paper developed a new topology for the single‐phase asymmetrical cascaded multilevel inverter and realized with optimal hardware components. This solution aids to substantially reducing the number of semiconductor switches and DC sources, henceforth reduces the gate drivers requirement. The proposed multilevel inverter creates a waveform with a high number of staircase voltage levels compromising with low total harmonic distortion at the outputs. The configuration is asymmetric and generates thirty‐one level different output voltages. MATLAB/Simulink numerical software used to verify the modeling and validated experimentally in laboratory scale prototype. The testing of the inverter executed under both steady state and dynamic load changing conditions. A set of numerical and experimental results are provided and shown clear evidence of satisfying the expectation with theoretical development. The proposed converter is well suitable for renewable energy applications.

“…However, this nonlinear characteristic leads more cogging torque on the motor, even if it is designed very well [6,7]. In order to achieve longer lifetime drivers, the modulation of switch and inverter design must be succeeded beside the control method [8][9][10][11]. This paper investigates the cogging torque issue of PMSM.…”

In this paper, active damping control based virtual positive impedance for a PMSM driver is proposed. The proposed model is assumed to achieve the better motor current with a better harmonic response. 6 switches can be employed in the design of the driver to obtain high performance with a simultaneous reduction in the motor current harmonics and thus the torque ripple of PMSM. However, the reduction of input current harmonics is very important to operate the PMSM with less cogging torque. The proposed concept offers a significant decreasing in harmonics. Thus, the effect of VPI on the cogging torque can be understood. The inverter with a Field Oriented Control (FOC) method operates in 3-phase and 20 kHz switching frequency. The PMSM motor is fed by the inverter. The VPI based active damping control for the motor drive is discussed to confirm the performance of the proposed method. The simulation results based on MATLAB are provided to validate the proposed control strategy.
