Comparative Analysis of Inverter Topology for Highly Efficient Single-Phase Photovoltaic Generation System

Article Preview

Abstract:

The distributed renewable energy sources as wind, photovoltaic, fuel cell, wave are getting more and more attention and research due to the continuous deterioration of environment and constant stress of energy crisis. In this paper, several widely used topologies in transformerless PV inverter are introduced at the beginning. Then, the pros and cons of various topologies are discussed and evaluated in detail with respect to leakage current, efficiency and cost. The final conclusions derived can be regarded as references for design of highly efficient single-phase photovoltaic generation system.
