An Asymmetric Extended Modular Transistor Clamped Multilevel Inverter – An Energy Efficient Systems

Abstract

In the research paper, a latest all-purpose Asymmetric Extended Modular Transistor Clamped H-bridge (AEMTCHB) Multilevel Inverter (MLI) using Cascaded H-bridge is planned. This research study is an effort to represent an MLI based on modular arrangement with very limited DC supply. This proposed EMTCHB topology requires a limited amount of DC supply voltage and switching components. This topology consists of limited switching components, which reflects lower complexity and lower overall expenditure of the inverter. Here in this proposed topology, capacitors are kept as a source of voltage supply. For proposed MLI, three algorithms are proposed to decide the amount of DC source voltage. These abilities received by comparing anticipated topology together with old conventional topologies on aforesaid point of analysis. Furthermore, in order to balance the voltage of capacitor, a new control scheme is proposed. Lastly, the desired performance of the proposed MLI is reconfirmed through simulation results on a 49-level EMTCHB MLI in MATLAB simulink software program.
