摘要：
The development on PV applications along with recent breakthroughs in power electronics has became in a strong research area especially in modeling and control techniques. This paper presents an analysis of grid-connected photovoltaic systems using three different high-order dc/dc topologies: Cuk converter, SEPIC converter and Zeta converter. This work considers ideal PV systems and a voltage load model is used, which is a common model for large DC-links. A technique for compensation of voltage oscillations is introduced as an alternative to the common use of electrolytic capacitors which introduce reliability problems. The systems are tested through simulation to validate the analysis performed and finally some conclusions about results are given.
