The development of static power converters capable of transforming DC energy obtained from alternative sources into AC has become one of the main challenges in renewable energy systems. In this context, this paper presents a novel topology of step-up/step-down single-stage DC-AC converter that works with fully controlled waveforms of output voltage and input inductor currents. It also promotes high...
This paper presents a low complexity system for characterizing Photovoltaic (PV) modules and strings in real-time, allowing accurate measurements and analysis of the actual power production of PV systems in real operation conditions. Applicability of this characterization system is in the real-time condition monitoring of such PV systems when suitable algorithms that make use of such current-voltage...
Alternative energy sources has been attracting great interest in the area of static converter development. This fact is related to issues like sustainability and the world environment, which is contributing to viability of this type of energy source. The main challenge is to develop systems that transform this DC energy in AC. Within this subject, this paper focuses the establishment of a new control...
