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

Control strategy of parallel three-phase four-leg inverter under unbalanced conditions
Dianzi Jishu Yingyong, 2019 A compound control strategy is proposed in order to solve the low control accuracy and poor anti-disturbance of deadbeat control. In this method, the repetitive control is embedded into the deadbeat control to improve the robustness of the control system
