[21] use non-nearest three vectors to synthesise the switching sequence, which replaces the vectors that increase NP potential imbalance with vectors that do not affect NP potential. In [22], virtual space-vector modulation is used to construct the virtual medium vectors by using the redundant ...
While an equivalent strain based criteria was used for fracture under Mode II failure in [18], the Mode III failure was simulated using a shear strain failure criteria proposed by Wen and Jones [19]. Using an implicit FEA numerical setup simulating the progression of damage between load steps...
Novel switching sequences have been proposed recently for a neutral-point-clamped three-level inverter, controlled effectively as an equivalent two-level i... S Das,G Narayanan,M Pandey - 《IEEE Transactions on Power Electronics》 被引量: 68发表: 2014年 Research of the Unity Theory Between Thr...
Extensive numerical results that are presented in this study include (i) convergence characteristics of computed deflections, moments and natural frequencies, and (ii) effects of length-to-thickness ratio, radius-to-length ratio, fiber orientation angle, lamination sequence and shell geometry on the ...
(ii) enable non-rotatable engagement with a front connector body of the connector assembly and with a backshell assembly of the connector assembly;(b) the termination ring includes one or more slots, each slot extends from the outer surface through the termination ring into the central passage,...
c. ratii, which has only one karyotypic profile reported. These banding patterns have been shown to be stable and reproducible over time. Low levels of genetic polymorphisms characterize the P.c. carinii karyotype forms. In the present study, a colony from Charles River Laboratories (Wilmington,...
The sound pressure distribution is derived by applying the Rayleigh integral, and the sound radiation efficiency is obtained in sequence. Sound transmission loss (STL) of the sandwich panel is also obtained in theory. Next, numerical simulations and experimental result are carried out to verify the...
Model Predictive Control with Reduced Common-Mode Voltage Based on Optimal Switching Sequences for Nested Neutral Point Clamped Inverter. IEEE Trans. Ind. Electron. 2024, 71, 27–38. [Google Scholar] [CrossRef] Monfared, K.K.; Iman-Eini, H.; Neyshabouri, Y.; Liserre, M. An Improved ...
Based on this representation, the momenta conservation is also satisfied since, in the limit of infinite wavelengths, the modulus of the phonon wave vector can be neglected compared to that associated with the incident and scattered waves: thus, both type I and type II phase-matching conditions ...
The other advantages offered by these (ZSI) inverters are: (i) no need for the time delay between the switches of the same leg, and (ii) better output voltage quality. Extensive research is present in the area of two-level ZSI, with the main focus on its topological improvements, PWM ...
