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 ...
26. The apparatus of claim 1 wherein one or more of the converter operating cycles comprise the following phases in sequence: (a) an energy-storage phase; (b) a first zero-voltage switching (“ZVS”) phase that begins at the end of the energy-storage phase; (c) an energy-transfer pha...
Free Vibration Analysis of Angle-Ply Laminated Circular Cylindrical Shells with Clamped Edges Kenji Hosokawa*, Masaki Murayama and Tosliiyuki Sakata Department of Mechanical Engineering, Chubu University 1200 Matsumotocho, Kasugai, Aichi, 487-8501, Japan ABSTRACT The free vibrations of angle-ply ...
(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 Distribution of switching sequence d Relationships among the vector sectors, switching states and three-phase modulation voltage In Fig. 2b, the three-level space vector has 27 vectors (switching states). They may be divided into four groups, namely, large vector (LV), labelled with VL1,…...
6 and 7, it can be seen that minimum and maximum values of is occur when vw is zero within both II and V current sectors. In these cases, a given is* may correspond to two different vw values: vw* and v˜w*. However, vw* should be chosen because it lies within the vw ...
sp. ratti is used to designate 'variant' [l]. These two populations are identified by distinct karyotypic profiles and fidelity and divergence from the small ribosomal subunit gene sequences originally reported for rat derived Pneumocystis [2,5]. Eight distinct banding patterns (forms) produced by...
This study proposes PWM schemes for three level diode clamped multilevel inverter (DC-MLI) which use an unpretentious switching sequence to determine the triangle for maximum output voltage and minimum CMV in entire modulation range. Here two types of approaches are proposed: (i) Partial ...
