一种基于Buck-Boost交流斩波器的高频链分相电压源微逆变器

This article proposes a novel single-stage high-frequency-link split-phase microinverter that utilizes dual buck–boost ac choppers to form a secondary-side cycloconverter. This design achieves high voltage gain and a wide voltage regulation range, allowing for a reduced turns ratio in the high-frequency transformer (HFT). Consequently, voltage stress on the secondary-side switches is minimized, an...
