Cascaded Transformers-Based Multilevel Inverters With NPC
IEEE Transactions on Industrial Electronics, 2022The basic structure and generalization of two cascaded transformer multilevel inverters (CTMIs) are proposed in this paper. Such configurations are based on cascaded symmetrical transformers coupled to two-level (2L) legs and three-level (3L) neutral-point clamped (NPC) legs. One configuration has a shared 2L leg, connected to all transformers.

Optimal design of NPC and Active-NPC transformerless PV inverters
2012 3rd IEEE International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2012Targeting at a cost-effective deployment of grid-connected PhotoVoltaic (PV) systems, this paper presents a new methodology for the optimal design of transformerless PV inverters, which are based on the Neutral Point Clamped (NPC) and the Active-Neutral Point Clamped (ANPC) topologies. The design optimization results demonstrate that a different set of
