Tradeoff Between Total Harmonic Distortion and Efficiency in Coupling of a Classical Bridge Inverter and a Photovoltaic System
Abstract
The diary availability of solar energy, the benefits of clean and renewable energy and the crescent tendency of distributed generation contribute to fast advance of photovoltaic systems. The process of energy generation with solar cells is in a continuous evolution, reaching each year higher levels of efficiency, which combined with the advancements in the power electronics field and semi-conductors technology in large scale production makes the utilization of the photovoltaic systems cheaper and more efficient. Therefore, investments in solar energy supplied houses, buildings, industries and transportation increase. Fig. 1 illustrates the cumulative growth in PV capacity in major solar energy producing countries from 1992 to 2009 (IEA PVPS Programme, 2009).
