Abstract
The invention discloses a single-phase inverter and a control method and system thereof, and the single-phase inverter comprises a Semi-Z source inverter. The input source is connected with the input side of the Semi-Z source inverter; the boosting module is connected with the output side of the Semi-Z source inverter; and the filtering module is connected with the boosting module. The invention provides an improved topology and control for a Semi-Z source inverter topology, and a novel double-end common-ground single-phase inverter is combined with the Semi-Z source inverter, so that the limitation that the gain is 1 is broken through, and high gain is realized, that is, the positive gain is infinite, and the negative gain is also infinite.
