Analysis of Different PWM Techniques for Enhanced Ultrahigh Gain Z-Network Topology

International Transactions on Electrical Energy Systems
In these modern times, the Z-source inverters (ZSIs) have become a revolutionary invention ever since the year 2002. The pulse-width modulation (PWM) technique used for most of the ZSIs is simple boost control PWM (SBC-PWM), and the SBC-PWM implies for a

Novel PWM Technique for Quasi Switched Boost Converter for the Nano-grid Applications

2019 IEEE 28th International Symposium on Industrial Electronics (ISIE), 2019
Scaled down version of the Micro grid is nanogrid, where each residential home, commercial building etc. are optimized and power is shared between the Battery Energy Storage (BES) and the utility grid. The recently proposed impedance source converters (ISC) are attractive solution for the nanogrid applications.

Null Killing Vector Dimensional Reduction and Galilean Geometrodynamics

, 1994
The solutions of Einstein's equations admitting one non-null Killing vector field are best studied with the projection formalism of Geroch. When the Killing vector is lightlike, the projection onto the orbit space still exists and one expects a covariant

Performance analysis of a new elevated gain switched inductor-based quasi-Z-source-T-type inverter for small-scale grid-tied WECS

Results in Engineering
Wind energy conversion systems (WECS) benefit greatly from minimizing the number of power conversion stages, as this simplification improves the overall system efficiency. Among the single-stage converter topologies, the quasi-Z-source inverter (qZSI) is
