This paper analyzes two maximum power point tracking (MPPT) converter topologies that are part of an interface converter for the integration of photovoltaics (PV) in the grid. Two different MPPT converter topologies (boost converter and quasi-Z-Source (qZS) converter) were selected and compared. Theoretical comparison includes an analysis of regulations for obtaining continuous source current and comparison of necessary parameters of the reactive elements of the systems. 270 W experimental prototypes of both converters were built and experimentally compared. Theoretical and experimental efficiency estimation is proposed and discussed. Also, the losses in diodes and MOSFETS are evaluated taking into account technical data from datasheets.
