摘要

In this paper, a single-phase single-stage (SPSS) photovoltaic (PV) inverter is proposed, which is capable of flexibly mitigating the impact of second-order ripple power and achieving the optimal maximum power point tracking (MPPT) algorithm using inherent-ripple-based extremum seeking (ES) method. A ripple power transferring circuit (RPTC) is employed in the proposed SPSS inverter, and a flexible ripple voltage transferring algorithm is proposed to cope with the trade-off between maximum acceptable ripple voltage across the DC-link capacitor and minimum operational requirement of the inherent-ripple-based MPPT algorithm.
