Abstract: This paper presents a new photovoltaic (PV) micro-inverter topology. The topology is based on a partial power processing resonant front end dc-dc stage, followed by an interleaved inverter stage.
Topologies of isolated microinverters Galvanic isolation exists between the grid and the PV modules in isolated microinverter types. The presence of a high-frequency transformer in the microinverter topology usually provides this isolation.
However, high-frequency transformers and high switching losses degrade the efficiency of the isolated types of microinverters. Recently, several isolated topologies were proposed to increase the efficiency and lifetime of PV converters. This paper presents a comprehensive review of the most recent isolated topologies of PV microinverters.
Among microinverter topologies, the single-stage flyback with soft switching is superior with respect to efficiency and cost. However, the lifetime of the converter is negatively affected. The only drawback of the interleaved flyback inverter with active clamp switching is its short lifespan.
Presently, the grid connected transformerless topologies are configured as high frequency transformerless topologies and low frequency transformerless topologies. This comparison shows that transformerless inverter topology is the best choice for grid-PV microinverters based on long lifespan, high efficiency, and lowest cost SPV converters. IV.
