ABSTRACTThe output AC side voltage of traditional full‐bridge inverter is lower than the input DC side voltage, which is limited in low‐voltage power generation. The conventional boost circuit and the modified boost circuit structure are effectively combined, thus putting forward a kind of no leakage current of single‐phase single‐stage booster inverter. The inverter has the characteristics of common ground, which can suppress the leakage current from the structure and avoid the problem of shoot‐through and improve the reliability of the system. The working mode, modulation strategy, and steady‐state performance of the proposed circuit structure are analyzed in detail. Finally, a 250‐W experimental prototype is designed in the laboratory, and the experimental results verify the feasibility and superiority of the proposed inverter.
