Digital control implementation for PV cell-level invertersDigital control implementation for PV cell-level inverters Πλήρης Δημοσίευση σε Συνέδριο Conference Full Paper 2024-10-032022enThis paper presents the design procedure of the digital control unit of an on-chip photovoltaic (PV) cell-level DC/AC inverter. Its main blocks are presented, along with their interconnections and timing, whereas the state diagram, based on the sinusoidal pulse width modulation (SPWM) is given, for both grid-tied and standalone operation. The proposed digital control unit is experimentally validated in a laboratory test bench, comprising four full-bridge (H-bridge) inverters in cascaded configuration. The TMS320F28379D microcontroller is employed, as it is suitable for such applications. Finally, experimental results indicate the operational characteristics of the proposed digital control scheme, being the first step for on-chip integration.This 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).http://creativecommons.org/licenses/by/4.0/11th International Conference on Modern Circuits and Systems TechnologiesProceedings of the 11th International Conference on Modern Circuits and Systems Technologies Delianidis Nick Rigogiannis Nick Papanikolaou Nick Siskos Stylianos Koutroulis Eftychios Κουτρουλης Ευτυχιος Institute of Electrical and Electronics Engineers Microcontroller H-bridge inverter On-chip converter PV cell PV inverter
