Abstract
Standalone power systems are becoming a suitable way of supplying telecommunications equipment, since they are being located in remote areas, which seems to be its nowadays and future trend location. Power electronics interfaces play an important role in these systems, because they are responsible for meeting load supply requirements. Photovoltaic (PV) generators are nonlinear sources, and behave mainly as DC current sources. As most telecommunications equipments operate from a DC supply voltage, the ideal power electronics interface to be used is a dc-dc converter. A literature survey showed that typical voltage source DC-DC converters are applied to photovoltaic generators, without many modifications. On the contrary, this paper presents a different DC-DC converter based on its current-source behaviour of a photovoltaic generator. © 2009 IEEE.| File | Dimensione | Formato | |
