The current work focuses on predicting the buckling and free vibration frequencies (fn) of cenosphere reinforced epoxy based syntactic foam beam under varying loads. Critical loads (Ncr) fn are predicted using differential quadrature method (DQM). Ncr have been calculated for beams volume fractions subjected to axial load clamped-clamped (CC), clamped-simply (CS), simply-simply (SS), clamped-fr...

Three-level Z-source inverters are recent single-stage topological solutions proposed for buck-boost energy conversion with all favorable advantages of three-level switching retained. Despite their effectiveness in achieving voltage buck-boost conversion, existing three-level Z-source inverters use two impedance networks and two isolated dc sources, which can significantly increase the overall ...

Multi-level inverter technology has emerged recently as a very important alternative in the area of high-power medium-voltage energy control. In this paper, the most important topologies like diode-clamped inverter (neutral-point clamped), capacitor-clamped (flying capacitor), and cascaded multi cell with separate dc sources. In this paper, we proposed a new multi-level inverter topology based ...
