The output voltage of a Multilevel Inverter (MLI) can be controlled using various low and high frequency modulation strategy. Apart from meeting the load voltage demand, the modulation strategy also tries to reduce the harmonics present in the output voltage waveform. In this paper, a novel modulation strategy, a Variable Structure Nearest Level Modulation (VSNLM) has been proposed with the objective to reduce the Total Harmonic Distortion (THD) thus giving better output voltage quality and smoother control. The development of the mathematical model and subsequent analysis has been carried out. Moreover, the proposed modulation scheme has been implemented on 7, 9, 11, and 13 level Cascaded H Bridge inverter and a generalized mathematical model of the proposed scheme has been developed. A comparison of the proposed strategy with the conventional NLC is presented in the paper. The results confirm the superior performance of proposed strategy in terms of THD. Experimental results have also been presented for validation.

“…The proposed technique has the advantage of equal power distribution in modules [16] as well as low THD in output voltage. The authors in [17] have proposed an 11 level MLI topology that utilizes SHE for the removal of lower-order odd harmonics. A projectile target algorithm is used to solve the non-linear transcendental equations.…”

A Fast Convergent Homotopy Perturbation Method for Solving Selective Harmonics Elimination PWM Problem in Multi Level Inverter

et al. 2021

Pulse width modulation (PWM) control for power converter has been vastly investigated and used. For medium and high power applications, low switching frequency PWM is preferred over high switching frequency-based PWM techniques such as carrier-based and space vector-based techniques. A preprogrammed low switching frequency-based PWM technique known as selective harmonics elimination (SHE) gives the better quality waveform at a lower switching frequency. The main difficulty in applying SHE PWM is in solving non-linear transcendental equations for obtaining switching angles. Several methods have been proposed that include numerical techniques, optimization techniques, and algebraic techniques. However, the computation of switching angles is still a challenging task in the application of SHE PWM. In this paper, a novel fast convergent homotopy perturbation method (HPM) is proposed to compute switching angles for a multilevel inverter. The solutions obtained by the proposed technique are as accurate as obtained by the algebraic methods with no dependency on the initial guess. The proposed technique can compute the higher number of switching angles with multiple solutions in some modulation index range. A prototype is developed, and the field-programmable gate arrays (FPGA) controller is used to validate the practical implementation of the computed switching angles.

“…In recent times, multilevel inverters (MLIs) have been used as a potential solution for DC to AC conversion for various applications such as renewable energy conversion systems, high power drives, a high-voltage direct current (HVDC) transmission system, a distributed power generation system, etc. The main advantages of MLIs are lower dv/dt stress, higher operating voltage with lower rating devices, and near to sinusoidal output voltage, which in turn reduces total harmonic distortion (THD) and fault-tolerant capability [1][2][3]. Conventional MLIs such as the neutral point clamped (NPC) inverter, flying capacitor (FC) inverter, cascaded H-bridge (CHB) inverter, and modular multilevel converter (MMC) have replaced the conventional two-level inverter for medium and high voltage applications [4,5].…”

A new triple voltage boosting switched-capacitor multilevel inverter (SCMLI) is presented in this paper. It can produce 13-level output voltage waveform by utilizing 12 switches, three diodes, three capacitors, and one DC source. The capacitor voltages are self-balanced as all the three capacitors present in the circuit are connected across the DC source to charge it to the desired voltage level for several instants in one fundamental cycle. A detailed comparative analysis is carried to show the advantages of the proposed topology in terms of the number of switches, number of capacitors, number of sources, total standing voltage (TSV), and boosting of the converter with the recently published 13-level topologies. The nearest level control (NLC)-based algorithm is used for generating switching signals for the IGBTs present in the circuit. The TSV of the proposed converter is 22. Experimental results are obtained for different loading conditions by using a laboratory hardware prototype to validate the simulation results. The efficiency of the proposed inverter is 97.2% for a 200 watt load.
