This paper presents Model predictive control technique for the high efficiency with reduced switches stresses T-type three-level Neutral Point Clamped (NPC) inverter for Photovoltaic (PV) applications. T-type three-level NPC inverter is a combination of the NPC and T-Type inverters. As it is a combination of T-type and NPC it has the same features of NPC such as breakdown voltage of the switching...
Dc structures are acquisitioning acceptance owing to its high efficiency, high reliability and easy interconnection of renewable sources as compared to ac systems. In standalone dc system, parallel dc-dc converters are used to interface storage element and loads. Use of master-slave controller for paralleling is restricted on account of its high cost, low reliability and complexity. Even though conventional...
