Experimental study of a low-voltage PV cell-level DC/AC converterExperimental study of a low-voltage PV cell-level DC/AC converter Δημοσίευση σε Συνέδριο Conference Publication 2023-05-242021enThis research has been co-financed by the European Regional Development Fund of the European Union and Greek national funds through the Operational Program Competitiveness, Entrepreneurship and Innovation, under the call RESEARCH – CREATE – INNOVATE (project code: T1EDK-01485).This paper focuses on the design of a low-voltage power converter for an on-chip PV cell-level inverter. Various topologies are discussed for the DC/DC stage, whereas the ZVS quasi-resonant boost and the synchronous boost are considered the most appropriate for this application. Both the aforementioned topologies are modeled and evaluated in terms of efficiency, by the aid of PSpice simulations. Due to requirements and limitations of the available 0.18 μm CMOS process technology, the synchronous boost is finally chosen as the most appropriate solution. As for the DC/AC stage, the H-bridge inverter configuration is selected, as a simple, compact and cost-effective solution. A prototype converter is designed and constructed with discrete components, so as to validate the functionality and performance of the proposed system. Finally, experimental results are presented, indicating the high efficiency that can be achieved.http://creativecommons.org/licenses/by/4.0/2021 10th International Conference on Modern Circuits and Systems Technologies Rigogiannis Nick Boubaris Alexandros Agorastou Zoi Papanikolaou Nick Siskos Stylianos Koutroulis Eftychios Κουτρουλης Ευτυχιος Institute of Electrical and Electronics Engineers H-bridge inverter PV cell PV inverter Synchronous boost converter ZVS quasi-resonant boost converter
