Photovoltaic system having power-increment-aided incremental-conductance maximum power point tracking controller using constant-frequency and variable-duty control and method thereof

摘要

The configurations of photovoltaic system and methods thereof are provided. The proposed photovoltaic system includes a PI-INC MPPT controller using a constant-frequency variable-duty (CFVD) control and guided by an Ipv-Vpv curve and a Ppv-Vpv curve.
