The dual‐buck full‐bridge grid‐connected inverter (DFGI) is well known as its no shoot‐through problem, high efficiency and high reliability, but the common‐mode leakage current exists in the positive half cycle. To solve the problems of common‐mode leakage current of the conventional DFGI, a new DFGI topology is proposed. The corresponding modulation strategy is presented. Meanwhile, on the basis of the theoretical analysis, it can eliminate the common‐mode leakage current of conventional DFGI. The experimental results prove the validity of the theoretical analysis.
