The traditional DC-link indirect AC/AC power converters (AC/DC/AC converters) employ two-stage conversion, which increases the circuit complexity along with gate driving challenges, placing an excessive burden on processor while implementing complex switching modulation techniques and leads to conversion losses due use of a large amount controlled semiconductor switches. On contrary, direct vol...

A maximum power point tracking algorithm for single-stage converters connecting photovoltaic panels to a single-phase grid is presented in this paper. The algorithm is based on the processing of current and voltage low-frequency oscillations introduced in the PV panels by the single-phase utility grid. The algorithm has been developed to allow an array of PV modules to be connected to the grid ...
