In this paper, a new Single Ended Primary Inductance Converter based dc- dc converter operate in boost mode is proposed. The designed by incorporating the quasi-Z source structure and switched capacitor cell. salient features of proposed are high range voltage gain, less stress across semiconductor devices efficiency. This characteristic creates gain an exceptional interface among load inside e...

In recent years, voltage source multilevel converters are very popular in medium/high-voltage industrial applications, among which the NPC/H-Bridge converter is a popular solution to the medium/high-voltage drive systems. The conventional finite control set model predictive control (FCS-MPC) strategy is not practical for multilevel converters due to their substantial calculation requirements, e...

A non-isolated DC/DC converter with high transfer gain is proposed in this paper. The presented converter consists of the switched inductor and three-level converters. The DC/DC power converter is three-level boost converter to convert the output voltage of the DC source into two voltage sources. The main advantages of DC/DC converter are using low voltage semiconductors and high gain voltage. ...

This paper introduces a cascaded converter structure using hybrid two-level cells to form single-phase seven-level inverter. Compared various conventional and existing multilevel (MLI) topologies, this topology requires lower number of devices. It uses several DC sources integrated in two-stage provide the required voltage. In topology, DC-link condensers are not necessary. The modes operation ...

This paper proposes a high voltage gain dc/dc converter with coupled inductor cells and switched capacitor for renewable energy applications. It includes coupled inductor, switched capacitor and voltage multiplier cell. Switched capacitor charged during off period by using the energy stored in the coupled inductor. This will increase the performance of the converter. The voltage gain of traditi...

let g be a fixed element of a finite group g. we introduce the g-noncommuting graph of g whose vertex set is whole elements of the group g and two vertices x,y are adjacent whenever [x,y] g  and  [y,x] g. we denote this graph by . in this paper, we present some graph theoretical properties of g-noncommuting graph. specially, we investigate about its planarity and regularity, its clique number a...
