Comparison between five-level and seven-level active neutral point clamped converter for photovoltaic energy generation

When the medium and high power applications are concerned, we are in need of multilevel converters. These converters can provide enticing solution for the renewable energy conversion. Developing high voltage rating converters of more than 6.6kV is a key goal for solar energy based industries. The utmost power capacity of the photovoltaic plants has extremely inflated over the past few years and it's expected to increase its capacity over the succeeding decade as the result of the increasing demand of renewable energy and distributed generation systems. This paper presents a seven-level active neutral point clamped (ANPC) inverter for the minimization of total harmonic distortion of voltage. The seven level active neutral point clamped converter is simulated using MATLAB software.
