Leakage Current Elimination of Four-Leg Inverter for Transformerless Three-Phase PV Systems [PDF]
IEEE Transactions on Power Electronics, 2016 Eliminating the leakage current is one of the most important issues for transformerless three-phase photovoltaic (PV) systems. In this paper, the leakage current elimination of a three-phase four-leg PV inverter is investigated. With the common-mode loop model established, the generation mechanism of the leakage current is clearly identified. Different

Switchless Power Decoupling and Switchless Leakage Current Elimination in Grid-Tied Inverters
2017 9th IEEE-GCC Conference and Exhibition (GCCCE), 2017 This paper presents a grid-tied single-phase transformerless inverter that eliminates simultaneously the leakage current issue and the double grid frequency power pulsation without additional active circuitry. The control scheme considers the full bridge inverter as two buck converters that are connected differentially with the utility grid.

Leakage Current Elimination Mechanism for Photovoltaic Grid-Tied Inverters
IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013The elimination of leakage current is of first importance for transformerless grid-tied photovoltaic (PV) inverters. A unified leakage current analytical model for single phase inverters, which unifies topologies of both transformer and transformerless, is presented in this paper. It is suitable for the analysis of leakage current elimination mechanism

Dual-Buck Full-Bridge Grid-Connected Inverter With Common-Mode Leakage Current Elimination [PDF]
Electronics Letters, 2018 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.
