A New General Topology for Cascaded Multilevel Inverters Based on Developed H Bridge
A new general cascaded multilevel inverter using developed H-bridges is proposed. The proposed topology requires a lesser number of dc voltage sources and power switches and consists of lower blocking voltage on switches, which results in decreased complexity and total cost of the inverter. These abilities obtained within comparing the proposed topology with the conventional topologies from afo...
متن کاملA New Topology for Cascaded Multilevel Inverters with Single Dc Input
This paper proposes two methodologies that are extended from the existing Cascaded Multilevel Inverter Employing Three-Phase Transformers and Single DC Input topology . The proposed circuit configuration can reduce the number of switches required to convert the input DC power into AC power when compared with traditional method. However Simulation results reveals that the THD variation of the pr...
متن کاملComparison between 7-Level Cascaded and 7-Level Diode-Clamped Multilevel Inverters for Feeding Induction Motor
In this study, two types of multilevel convertors, cascaded multilevel inverter with separate DC sources and diode clamped multilevel inverter with common DC source are modeled and compared in the case of feeding of an induction motor. Here, SHEPWM technique is used as the switching strategy. Also a new variable torque feedback control on modulation index is presented, to preserve the induction...
متن کاملTwo New and Novel Cascaded Multilevel Inverters with Less Number of Components Utilizing Series Submultilevel Inverters
In this paper, two new cascaded inverters are proposed, by using the series connection of new Submultilevel inverters. Each of the proposed Submultilevel inverters consists of three batteries and eight power switches. Four algorithms are presented to determine the voltages of these batteries for each of the proposed structures. In this study the comparison between the proposed structures with c...
متن کاملSelective Harmonic Minimization method For Cascaded Multilevel Inverters using ANNs
The dc sources that feed the multilevel inverter are varying in time, and the switching angles should adapt to the dc source variations. Any variations in the input will result in harmonics at the output. To mitigate the harmonics in the inverter output, GA is used. A genetic algorithm optimization technique is applied to determine the switching angles for a cascaded multilevel inverter. Then, ...
