“…Generally, multilevel modulation strategies can be classified, according to the switching frequency, into two categories: high-frequency switching and low-frequency (fundamental frequency) switching methods. The most popular modulation schemes discussed in the literature for multilevel inverters are multireference/multicarrier-based PWM [4], [5], [9], [10], multilevel space-vector PWM (SVM) [11], [12] and multilevel selective harmonic elimination (SHE) [7], [13]. The multilevel carrier-based PWM and SVM techniques are considered high-switching frequency schemes, whereas SHE falls within the low-switching frequency group.…”

This paper presents an implementation of selective harmonic elimination (SHE) modulation for a single-phase 13-level transistor-clamped H-bridge (TCHB) based cascaded multilevel inverter. To determine the optimum switching angle of the SHE equations, the Newton-Raphson method is used in solving the transcendental equation describing the fundamental and harmonic components. The proposed SHE scheme used the relationship between the angles and a sinusoidal reference waveform based on voltage-angle equal criteria. The proposed SHE scheme is evaluated through simulation and experimental results. The digital modulator based-SHE scheme using a field-programmable gate array (FPGA) is described and has been implemented on an Altera DE2 board. The proposed SHE is efficient in eliminating the 3 rd , 5 th , 7 th , 9 th and 11 th order harmonics, which validates the analytical results. From the results, it can be seen that the adopted 13-level inverter produces a higher quality with a better harmonic profile and sinusoidal shape of the stepped output waveform.

“…This strategy is based on comparison between several triangular signals to a sinusoidal reference [9][10][11][12]. In the case of fivelevel converter the strategy consists of comparing four triangular carries having the same frequency and amplitude to the sinusoidal reference.…”

Multilevel inverters (MLIs) have been preferred over conventional two-level inverters due to their inherent properties such as reduced harmonic distortion, lower electromagnetic interference, minimal common mode voltage, ability to synthesize medium/high voltage from low voltage sources, etc. On the other hand, they suffer from an increased number of switching devices, complex gate pulse generation, etc. This paper develops an ingenious symmetrical MLI topology, which consumes lesser component count. The proposed level dependent sources concoction multilevel inverter (LDSCMLI) is basically a multilevel dc link MLI (MLDCMLI), which first synthesizes a stepped dc link voltage using a sources concoction module and then realizes the ac waveform through a conventional H-bridge. Seven level and eleven level versions of the proposed topology are simulated in MATLAB r2010b and prototypes are constructed to validate the performance. The proposed topology requires lesser components compared to recent component reduced MLI topologies and the classical topologies. In addition, it requires fewer carrier signals and gate driver circuits.
