A Critical Review on Photovoltaic Base Maximum Power Generation System

This paper focuses on the review of solar systems, converters and control techniques of MPPT with power generation. Photovoltaic cells provide an additional method of acquiring energy, converting sunlight directly into electricity through the use of semiconductors. Effective photovoltaic implementation is reviewed, focusing on semiconductor properties and overall photovoltaic system configuration. Solid-state switch-mode converters have reached a matured level for improving power quality reduced total harmonic distortion and precisely regulated dc output by Buck, Boost, Buck -Boost & Cuck regulators and also about the multilevel inverter topology. This paper deals with a comprehensive review of power converters and inverters unit. The photovoltaic generators have a nonlinear V-I characteristics and maximum power points which vary with the illumination level and temperature. Using maximum power point tracker (MPPT) with the intermediate converter can increase the system efficiency by matching the PV systems to the load. This paper presents a maximum power point tracker based on different control schemes for a single-phase or three-phase and multilevel inverter connected to the utility grid.
