A New Single-Source Nine-Level Quadruple Boost Inverter (NQBI) for PV Application

Project Code :TEPGPE191


The main objective of this project is to evaluate the performance of the nine-level quadruple boost inverter (NQBI) topology


This paper introduces a nine-level quadruple boost inverter (NQBI) topology powered by one solar photo-voltaic source using fewer capacitors, switches, and diodes when compared to the other SC-MLIs topology. The suggested NQB inverter produces nine levels of voltage in its output by efficiently balancing the voltages of the two capacitors. The various SC-MLIs are compared in order to highlight the benefits and drawbacks of the proposed nine-level quadruple boost inverter (NQBI) topology. To validate the efficacy of the proposed solar photovoltaic based NQBI without grid connection, the performance of the proposed topology is validated through the MATLAB-based simulations.

Keywords: NQBI, reduced switch count, switched capacitor inverter, SPWM technique
