Topic : An Asymmetric Multilevel Inverter Topology for PV Applications with Reduced Number of Power Electronic Components
Authors:K.Srinivasu || S.M.Shariff , Dr. K.Satyanarayana
Abstract:Multilevel inverter performance is high compared to the conventional two level inverters due to their reduced harmonic distortion, lower electromagnetic interference. However the main drawback of multilevel inverter is increased number of switches, complex pulse width modulation control and balancing of capacitor voltages. This paper proposes a single phase fifteen level inverter for photo-voltaic applications. The proposed inverter topology consists of fewer components with low complexity gate drives and control signals. This paper also presents the most relevant control and modulation methods like Staircase modulation technique with sinusoidal wave as reference. In this paper also studied proposed multilevel inverter topology for both symmetric and asymmetric configurations. Proposed multilevel inverter is compared with already existing inverter topologies. The entire system is numerically simulated using MATLAB/SIMULINK and the simulation results are presented..
