Analysis and Simulation of Asymmetrical Current Source Multilevel Inverter
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 2
Abstract
This paper presents asymmetrical current source multilevel inverter approach for high power output applications. The topology used here is derived from the multilevel voltage-source inverter (MVSI) by dual conversion, this allows the wealth of existing knowledge relating to the operations, modulations and control strategies of multilevel VSI to be immediately applied to such multilevel CSI. It is based on the parallel connection of the Hbridge inverter cells using different control techniques. Simulation of asymmetrical current source multi level inverter is shown using 2 and 3 H-bridge inverter cells with parallel connection using optimization angle control technique. Now ever by the supplies which are in GP with different ratios like 2,3, etc. The proposed configuration is shown for 7,9, 15 and 27 level inverters having inherent advantages of the H-bridge multi level inverters. Structural and operational characteristics are discussed and their inherent advantages are shown. Simulation using Matlab Simulink is done to verify the performance. Simulation and results for this proposed scheme are presented in this paper.
