Application specific harmonic performance evaluation of multicarrier PWM techniques

THD Minimization Based Asymmetrical Cascade Multilevel Inverter with Different Modulation Techniques

“…There are nine sufficient switching modes in generating the multistep level for a 9-level MLI. There are four different pulse width modulation strategies as given below [14][15][16].…”

Fpga Controlled Cascaded Mli With Advanced Multilevel Strategies For Harmonic Reduction

“…A very popular method in industrial applications is the classic carrier-based sinusoidal PWM developed by L.Tolbert et.al. [12] and Y.Liang et.al [13], that uses the phase-shifting technique to reduce the harmonics in the load voltage .Another interesting alternative is the SVM strategy, which has been used in three-level inverters as mentioned by V.G.Agelidis et.al [10]. B.N.Mwinyiwiwa et.al.…”

New Cascaded H-Bridge Multilevel Inverter Topology with Reduced Number of Switches and Sources

“…Among these PWM methods SPWM is the most used for the multilevel inverter, because it has very simple and easy to implemented. In this paper present SPWM method with the different carrier based disposition PDPWM, PODPWM and APODPWM has been analyzed [12] It is generally accepted that the PD strategy gives rise to the lowest harmonic distortion for the line-to-line voltage [13] [14].Any semiconductor switches have already been proposed.In this proposed concept uses the MOSFETs semiconductor switches. MOSFETs are preferred in: High frequency applications (1MHZ), Wide line or load variations, Long duty cycles, and Low-voltage applications (500V).…”
