Abstract :
Compared to the central inverter utilized in PV power generation system, modularized dc-ac converter becomes more and more popular. Dealing with hundreds of watts of energy, these micro-Photovoltaic (PV) inverters convert solar energy of each PV panel to the utility individually, with significant improvement of overall system reliability. This paper presents a case study of a single-phase micro- PV inverter, with a topology of reduced switching devices and galvanic isolation. Circuit analysis and its parameters calculation are carried out in details. Besides, a model of the proposed circuit has been built and demonstrated through simulation based on MATLAB/Simulink. The result proves the analysis of the circuit and provides theoretical validation for further research.
