With the growing adoption of renewable energy, research on microinverters has attracted significant research interest. Compared to traditional two stage topologies, single stage topologies offer higher efficiency and power density by reducing the component count and simplifying the structure. This paper introduces a novel modulation based on the single stage microinverter topology. A comprehensive theoretical analysis of zero voltage switching (ZVS) conditions for all switches for all phase angles is presented. Additionally, the RMS current optimization is conducted for better efficiency. Experimental results are conducted to verify the ZVS performance.
