Design and Simulation of an Asymmetrical 11-Level Inverter for Photovoltaic Applications

摘要

Increasing demands of power conversion technology encourages multilevel converters emerge as a solution to overcome limitations at power ratings in conventional methods of power converters. This paper discusses about a new asymmetrical construction of an 11-level inverter, despite the focus on the following design, few comparisons of the conventional topological construction will be stated. Limitations in conventional types topologies often deals with its complexity and volume. It will be furthered mentioned how the asymmetrical topology of the 11-level inverter design deals and overcome these limitations and reduce harmonic distortions for grid-tied PV systems. The proposed construction is designed and simulated by PSIM software. Analysis of Real-Time Simulation of the proposed design results in a THD value of 1.19%.
