“…This term will be present in the inverter phase voltages but not present in the line voltages. These two methods are equivalent under certain circumstances and extensive research comparing and contrasting the methods is available [12,13,14]. It is not possible to use injection of a third harmonic reference term with a 4-wire inverter because the injected signal will also be present in the phase voltage of the loads.…”

“…The approach to determine the duration of such pulses is what constitutes the difference among various PWM methods [19]- [21]. For example, in conventional SPWM, which is an analog domain method, the duration of each pulse is found through comparison of a sinusoidal reference waveform and a triangular carrier waveform.…”

Abstract-This paper proposes a method for optimization of the harmonic performance of converters under space vector modulation (SVM) control. It is shown that SVM provides a number of degrees of freedom, which make it suitable for optimization, subject to desired constraints. An objective function is defined, which seeks to minimize the most significant harmonic components of the generated waveform while keeping other harmonic components within the acceptable range outlined in the available standards. Since the formulation of the problem involves both real and integer variables, specialized optimization methods capable of handling mixed-integer variables need to be employed, and hence, a genetic algorithm optimizer is used to solve the optimization problem. Optimized SVM sequences obtained for various operating points under different sampling frequencies are shown to result in significant reduction of dominant harmonics while maintaining the waveform quality within prescribed limits.

“…wide linear modulation range -less switching losses -decreased total harmonic distortion(THD) -easy implementation and less computational time [4], [5]. The space vector pulse with modulation (SVPWM) technique provides superior harmonics capacity and solves the problem of unbalanced capacitor voltages by using redundant states in the space voltage vector plane.…”

This paper presents an optimized space vector pulse-width modulation (OSVPWM) technique for a five-level cascaded H-bridge (CHB) inverter. The space vector diagram of the five-level CHB inverter is optimized by resolving it into inner and outer two-level space vector hexagons. Unlike conventional space vector topology, the proposed technique significantly reduces the involved computational time and efforts without compromising the performance of the five-level CHB inverter. A further optimized (FOSVPWM) technique is also presented in this paper, which significantly reduces the complexity and computational efforts. The developed techniques are verified through MATLAB/SIMULINK. Results are compared with sinusoidal pulse-width modulation (SPWM) to prove the validity of the proposed technique. The proposed simulation system is realized by using an XC3S400 field-programmable gate array from Xilinx, Inc. The experiment results are then presented for verification.
