Abstract

This paper introduces a novel single-phase five-level switched-capacitor multilevel inverter (5L-SCMLI) topology distinguished by self-voltage balancing and intrinsic voltage enhancement capabilities. Without an extra DC-DC boost converter or transformer, the proposed topology (PT) provides a voltage gain factor of two. The PT produces a five-level output voltage utilizing only eight switches and two capacitors, hence offering a more compact, cost-effective, and efficient design. The proposed design implements the PWM technique for the smooth operation of the PT. A comprehensive comparison with the current SCMLI design highlights the PT benefits. To assess the usefulness of the proposed methodology, extensive simulations and experimental investigations have been executed to confirm the effectiveness of PT. The PT stands out as the most cost-effective design at only 73.44 USD.
