RAMOS PAJA, Carlos Andrés; PETRONE, Giovanni  e  SAAVEDRA MONTES, Andrés Julián. Compensation of DC-link voltage oscillations in grid connected PV systems. Rev.fac.ing.univ. Antioquia [online]. 2012, n.63, pp.82-92. ISSN 0120-6230.

This paper presents a compensation technique to mitigate the effect of DC- link voltage oscillations on PV systems. The main features of the technique are: the compensation is applied directly to the duty cycle, so it is simple to integrate with traditional maximum power point tracking systems; and the compensation calculation does not depend on the systems parameters, so its design is general. Explicit equations are provided for PV systems based on Boost, Buck and Buck-Boost dc/dc converters. Finally, the proposed approach is experimentally verified.

Palavras-chave : PV system; dc/dc converter; grid connection; maximum power point trac.
