“…Usually, this is done offline, using optimization techniques such as the Newton-Raphson (NR) method [14]- [17]. More complex techniques such as the genetic algorithm (GA) [15], [18]- [20] and the particle swarm optimization (PSO) [15], [21], [22] have also been demonstrated. Although these new techniques are fast in determining the optimized angle, the solutions only minimize the harmonics rather than eliminate them.…”

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.

“…In this paper, the heuristic Particle Swarm Optimization (PSO) technique is employed. This technique has been used in several optimal modulation techniques [12], [19], [30]- [32], [34] and shows superior characteristics in comparison with other heuristic optimization methods such as Genetic Algorithm, Simulated Annealing, etc. The obtained solutions of the equations are shown in Fig.…”

“…The high order harmonics are also weakened by passive filters. The main goals in the SHE-PWM method are the use of fast and effective optimization techniques to find a wide range of answers from non-linear equations [18], [19], and to find solutions for increasing the converter efficiency [9], [20]. In addition, employing a real-time SHE-PWM technique when the modulation technique does not use any look-up table saves switching angles versus modulation indices [21].…”

In this paper, the Selective Harmonic Mitigation-PWM (SHM-PWM) method is used in single-phase and three-phase Cascaded H-Bridge (CHB) inverters in order to fulfill different power quality standards such as EN 50160, CIGRE WG 36-05, IEC 61000-3-6 and IEC 61000-2-12. Non-equal DC link voltages are used to increase the degrees of freedom for the proposed SHM-PWM technique. In addition, it will be shown that the obtained solutions become continuous and without sudden changes. As a result, the look-up tables can be significantly reduced. The proposed three-phase modulation method can mitigate up to the 50th harmonic from the output voltage, while each switch has just one switching in a fundamental period. In other words, the switching frequency of the power switches are limited to 50 Hz, which is the lowest switching frequency that can be achieved in the multilevel converters, when the optimal selective harmonic mitigation method is employed. In single-phase mode, the proposed method can successfully mitigate harmonics up to the 50th, where the switching frequency is 150 Hz. Finally, the validity of the proposed method is verified by simulations and experiments on a 9-level CHB inverter.

Abstract--Power electronic converter-fed high performance AC drives belong to high-tech industry and are one of main factors for energy saving and productivity growth. This paper reviews present state and trends in development of key parts of controlled induction motor drive systems: converter topologies, modulation methods, as well as control and estimation techniques. Following topologies are described: Two-and Multi-level Voltage Source Converters, Current Source Converters and Direct Converters. Among the modulation techniques are briefly presented: conventional bipolar and unipolar PWM, space vector modulation (SVM) with extension for multilevel converters, harmonic control techniques, variable frequency modulation (hysteresis, nearest level, and model predictive techniques). About the control strategies, the generic torque control methods are described in two groups: linear and nonlinear controllers. In linear group are presented field oriented control (FOC), direct torque control (DTC) with voltage SVM, and DTC with flux vector modulation (DTC-FVM). The group of nonlinear control include: classical switching table based hysteresis DTC, direct self control (DSC) and predictive DTC scheme. Also, selected simple flux vector observers/estimators are discussed.
