چکیده
This paper presents a comprehensive review on three basic types of multilevel inverters i.e., diode-clamped, flying-capacitor, and cascaded H-bridge multilevel inverter and their variation for photovoltaic power system. The electrical power generated form photovoltaic power system is in DC form. Hence, it is necessary to be controlled and converted to useful form. Inverter is a power electronic device which is used to convert the DC power into AC form at desired output voltage and frequency. Multilevel inverters nowadays become interesting area in field of electric power system because it has the capability to produce staircase AC output voltage waveform without using a bulky passive filter. The state of art of multilevel inverter technology for photovoltaic power system has been presented in this paper, which will be very helpful to the researchers to trace the drawbacks in this field of research and thereby will provide information to resolve the existing issues in the near future.
