In addition, the output voltage of these sources is relatively low and, in general, a high DC bus voltage is required. And among the elements of the photovoltaic conversion chain that impose certain limitations are the choppers and especially the high-gain Z-source converters that play an important role in the interface between the photovoltaic panels and the DC bus. These converters have better efficiency and gain characteristics than conventional converters.frHacheur boost, Z-source, MPPT, GPVThesis
