Simulated Evaluation of Modern Multilevel Inverter Topologies

Abstract

One of the important components in the electrical system is the inverter which converts the DC energy stored in the battery banks to AC energy that is used by consumers or connected to power grid. As the current trend needed cleaner power supply, higher output power, less losses and almost free from harmonics, people are looking forward for better inverter. A conventional multilevel inverter is no more relevant to cope up with the requirements. Nowadays, to overcome the said problems is the point of concern for industries and researchers. In this paper new multilevel inverter topologies are referred over conventional ones as the quality of output voltages improves with the number of voltage steps at the output. These new topologies utilizes fewer power electronics components to generate a specific number of output voltage levels in comparison with the traditional multilevel inverters resulting in compact, reliable, efficient and economical solution.
