| Abstract: | This paper proposes an innovative hybrid multilevel inverter topology operating with a single DC voltage source to provide high output voltage levels. The High Frequency Link (HFL) in the proposed topology has two distinct secondary windings with midpoints, each supplying a Switched Rectifier (SR). Due to the midpoint, each SR circuit outputs either 1 VDC or 2 VDC levels. The two SR outputs, along with the main source at the primary side, are connected to a Packed U-Cell (PUC) inverter providing more levels than the conventional rectifiers. In this system, the number of output voltage levels of a standard 8-switch PUC circuit is increased from 13 to 29 with only two additional power switches. Consequently, the switching losses are minimized, and the total harmonic distortion is reduced from 6.47 to 2.88% by utilizing the Nearest Level Control strategy operating at the fundamental frequency without the need for complicated Pulse Width Modulation techniques. With the innovative HFL circuit, the voltage level gain is maximized, while the use of the main source significantly reduces the transformer size and cost. Comparisons in the literature demonstrate that the proposed topology has lower values in terms of the total fixed voltage and cost factor, thereby offering cost-effectiveness. In addition, owing to the asymmetric voltage configuration, it offers a suitable alternative for applications requiring high harmonic performance such as renewable energy systems and electric vehicles. Experimental results have validated the simulation results. This structure, which can meet IEEE 519 standard without the need for a filter, significantly contributes to the literature with its low cost and superior harmonic performance.
