Summary:To minimise the dependence on fossil-fuels, researchers focused on integrating renewable energy with different power electronic inverters. In that process multilevel inverters (MLIs) have gained more attention due to its impeccable advantages. In this work, a novel topology with boost ability, and reduced number of components is proposed. Capacitors used in the proposed structure possess self-balancing ability and the works competently under any loading condition. It is worthy to mention that the blocking voltage of proposed circuit is with in the limits of source voltage even with the dual boost. Sinusoidal pulse width modulation switching strategy technique is employed to get gating signals. Simulation using MATLAB is carried-out to assess the performance of proposed inverter. Further, the proposed circuit is compared with switched-capacitor (SC) based MLIs in terms of number of switches, and standing voltage to highlight the potential merits.
