Comparative investigation of 15 Level and 17 level cascaded h-bridge MLI with cross h-bridge MLI fed permanent magnet synchronous motor

Abstract

Multilevel inverters offers eminent solutions to high voltage high power applications due to the association of several devices in a series configuration. In this paper, a comparative investigation of both 15 and 17 level cascaded h-bridge multi level inverter with cross h-bridge fed permanent magnet synchronous motor are presented by appropriate simulations and mathematical analysis. Comparative analysis includes Inverter output voltage and current, number of switching devices, stator current and speed of PMSM and total harmonic distortion levels. Limitation of several switching devices, which can afford high voltage in the inverter is the major problems raised in this study. The advantage of this analysis is to figure out the appropriate inverter that can be used for real time application by considering the factors via. Harmonic distortion, output voltage, current, number of switching devices etc. Validation of the analysis is processed through matlab/simulink platform.

Comparative Exploration of 19-level and 21-level Cascaded H- Bridge MLI with Cross H-Bridge MLI

“…In CRHB MLI the voltage stress across switches S1, S2, Sn-1 and Sn is Vdc and other switches voltage stress is 2Vdc and the voltage stress of all switches in CHB MLI is Vdc [18][19][20]. The total voltage stress of CHB MLI and CRHB MLI is = 2*(𝑉𝑉 𝐿𝐿 − 1)* Vdc where 𝑉𝑉 𝐿𝐿 is level of output voltage.…”

A Review on Data Discrepancy Factor Performance for Industrial Applications using Clustering Algorithms

“…The substance in table6 shows the quantity of bunches shaped in three datasets by utilizing grouping calculations. Examinations of the current K Means and Hierarchical agglomerative calculations and proposed K-0HDQ ¶V calculation sets aside less effort to shape the different groups in given datasets [7]. The primary basic standard close to bunching examination is to arrange and parting informational index based on innate data related inside the aftereffect of such bunching measure is gathering of information focuses on an informational collection, where the items inside a gathering has an enormous arrangement of likeness and a low level of closeness with objects in different gatherings A critical field inside writing is references of articles distributed in different diaries.…”
