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 by using a single-stage converter. This simple structure yields higher efficiency and reliability when compared with standard solu-tions based on double-stage converters configuration. The proposed maximum power point tracking algorithm has been numerically simulated and experimentally verified by means of a converter prototype connected to a single-phase grid.

Abstract
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 by using a single-stage converter. This simple structure yields higher efficiency and reliability when compared with standard solu-tions based on double-stage converters configuration. The proposed maximum power point tracking algorithm has been numerically simulated and experimentally verified by means of a converter prototype connected to a single-phase grid.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
