Leakage Current Minimization Using NPC DC Decoupling Method for Three-Phase Cascaded Multilevel PV Inverter

This brief presents a new neutral point clamped (NPC) DC decoupling method based three-phase three-level cascaded multi-level inverter (CMLI) for the minimization of leakage current in PV systems. The proposed CMLI reduces the transitions in the terminal and common-mode voltage during common zero st...
