“…In this technique, the objective function is not needed. From the switching angle trajectory of RGA, PSO and FFA, it is observed that the variation of switching angles is linear irrespective of number of angles [18]. Due to the linearity nature, the switching angles are derived using formula as given below.…”

Original scientific paper In this paper, a real time implementation of selective harmonic elimination pulse width modulation (SHEPWM) using a new technique known as Linearization Method for single phase Matrix converter (SPMC) is designed and discussed. SHEPWM for SPMC is designed using Real coded genetic algorithm (RGA), particle swarm optimization (PSO) and firefly algorithm (FFA). From the switching angle trajectory of these techniques, the trajectory of LM is designed. In the proposed technique, the optimum switching angles are obtained using simple mathematical calculations. A MATLAB simulation was carried out and FFT analysis of the simulated output voltage waveform confirms the effectiveness of the proposed method. An experimental setup was also developed and the switching angles and firing pulses are generated using Field Programmable Gate Array processor. The proposed method proves that it is much applicable in the industrial applications by virtue of its suitability in real time applications.

“…The problem defined by (4)-(6) can be solved using any of the techniques that have been previously applied to the case of the more restrictive quarter-wave symmetry problem, including iterative approaches [6], [7], resultant theory [5], minimization techniques [2], [3], and [15] or genetic algorithms [4], [9], and [10]. Any sets of solutions resulting from the case where the quarter-or half-wave symmetry are followed will also be a solution to the more generalized formulation proposed in this letter.…”

Abstract-Selective harmonic elimination pulse width modulation (SHE-PWM) techniques offer a tight control of the harmonic spectrum of a given voltage waveform generated by a power electronic converter along with a low number of switching transitions. These optimal switching transitions can be calculated through Fourier theory, and for a number of years quarter-wave and half-wave symmetries have been assumed when formulating the problem. It was shown recently that symmetry requirements can be relaxed as a constraint. This changes the way the problem is formulated, and different solutions can be found without a compromise. This letter reports solutions to the switching transitions of a five-level SHE-PWM when both the quarter-and half-wave symmetry are abolished. Only the region of high-modulation indices is reported since the low-modulation indices region requires a unipolar waveform to be realized. Selected simulation and experimental results are reported to show the effectiveness of the proposed method. Index Terms-Five-level inverter, inverter control, non-symmetrical pulsewidth modulation (PWM), selective harmonic elimination (SHE).
