An overview of inverter topologies for photovoltaic electrical energy

This paper presents a general overview of photovoltaic power generation technology, the development of associated technologies and components, PV infrastructure, and, why there is now significant attention to PV systems. The paper explores current research and proposed topologies and their similarities and differences are discussed as well as the advantages and limitations of each design topology. A review of current research aims atidentifying where the industry is headed in terms of technological advances in the manufacture of inverter. This paper also shows that PV inverter technology is improving by leaps and bounds and that those improvements are largely based on better design principles and the reduction of needless components such that costs are decreased and efficiencies are increased.
