This paper demonstrates the performance of a new innovative photovoltaic microinverter topology with high power quality and efficiency. This inverter is based on coupling a boost converter with a discharge circuit to provide a rectified sine wave voltage.
In the first part of this paper, we describe the proposed topology and its operating principle as well as the simple and robust control system used. We also verify the stability of the system using the Lyapunov method. In the second part, we present the simulation results and discuss the influence of the load nature on the total harmonic distortion (THD) and on the efficiency.
