Research output: Contribution to journalArticlepeer-review


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.
