This article states that a unique 1P boost-buck converter associated with 3 level negative point clamped inverter with unbiased Dc source merged with the solar systems that could improve the non-stable situations usually created with the impartial solar systems. The projected scheme will concurrently assure the MP-point tracking each solar system and the output waves with high quality. As analyzing with the conventional 2 level solar inverting system, the projected NPC brought solar system with required voltage and the dc link storage devices. Additionally the performance and stability were discussed and verified by the MATLAB tool and prototype of the hardware system is subjected to the 3L NPC inverting system. © 2020 Elsevier B.V., All rights reserved.
