Microinverters connect a single photovoltaic (PV) module to the grid, and therefore require a high voltage step-up conversion ratio. This is usually achieved in a two-stage approach with a step-up DC-DC converter followed by a step-down inverter. More recently single-stage step-up inverters have been proposed under the assumption that less stages improves efficiency. This paper compares these two approaches and proposes an alternative solution based on a two-stage configuration consisting of a step-up DC-DC converter followed by a step-up inverter, distributing the elevation ratio among the two stages.
