Low power inverter mounted on each photovoltaic (PV) panel, i. e., microinverter is gaining popularity due to the increased energy harvest. This paper proposes a novel single-stage zeta microinverter for PV applications. The proposed topology is based on zeta converter with high-frequency transformer isolation and a single low side switch on the primary side of transformer. The most distinctive feature of the proposed inverter is its ability to work in continuous conduction mode (CCM) over a wide load range, which results in high efficiency, reduced current stress, and components' rating. All the secondary switches operate at line frequency, thus reducing switching losses significantly. A comprehensive study of the proposed microinverter, including steady-state analysis and design, has been reported. A 220-W microinverter was designed, developed, and tested in the laboratory. Experimental results are demonstrated to verify the CCM operation of the inverter and its performance over a wide load range.
