This paper evaluates eight module inverter topologies and provides an overview of the merits and demerits of each on the basis of circuit level Pspice simulation. The complete system is modeled in Pspice and the model is made as realistic as possible by including the parasitic elements. Only the output stage is varied for different topologies keeping the system model unaltered with the same control system and degree of demodulation so as to differentiate the variation of efficiency of these topologies. The purpose of the analysis is to determine which of this topology would be a best fit for the system and what are the compromises to be made (if any) to select one of these topologies as the output stage in the PV system.
