Multilevel Inverter For Solar Power Applications
L.Pattathurani,  Rajat Kumar Dwibedi,  Dr. S.S Dash
Multilevel voltage source inverters offer several advantages compared to their conventional counterparts. Synthesizing the AC output terminal voltage from several levels of voltages, staircase waveforms can be produced, which approach the sinusoidal waveform with low harmonic distortion, thus reducing the filter requirements. By increasing the level of the inverter we can get several advantages: get a good voltage wave form, Very low THD, reduced volume and cost. The need of several sources on the DC side of the converter makes multilevel technology attractive for photovoltaic applications. This paper provides an overview of a multilevel inverter topology and investigates their suitability for single-phase photovoltaic systems. A simulation model is based on MATLAB/SIMULINK is developed. An experimental 40W prototype inverter is built and tested. The results experimentally validate the proposed PWM based three H-bridge 27 level cascaded multilevel inverter.
Keywords- Cascaded H-bridge multilevel inverter, Dc link voltage, Total Harmonic distortion, Metal Oxide Semiconductor Field Effect Transistor, Insulated Gate Bipolar Transistor, Flexible AC Transmission System.
