A Cost-Effective and High-Efficiency Novel 15-Level Hybrid MLI Topology for Renewable Energy Systems
In this paper, a new hybrid model for single DC source multilevel inverters (MLIs) is proposed. The proposed switched diode (SD) and high frequency link (HFL) hybrid structure utilizes a single DC source voltage and supplies multiple DC voltages to the PUC circuit.

| description | In this paper, a new hybrid model for single DC source multilevel inverters (MLIs) is proposed. The proposed switched diode (SD) and high frequency link (HFL) hybrid structure utilizes a single DC source voltage and supplies multiple DC voltages to the PUC circuit. The MLI generates 15 levels in the output voltage waveform using only 8 power switches. It reduces the control complexity and provides a cost-effective solution with a low-cost function (CF) value of 2.71. A comprehensive comparison with recent work in literature has been made. Unlike most studies, it uses HFL for voltage gain. Most of the load current is drawn directly from the input source and a small portion is drawn through the high frequency transformer. This significantly reduces transformer size and costs. In tests with inductive loads, the output is near pure sinusoidal waveform. The total harmonic distortion (THD) is measured as 1.41% with a low inductive load of 50Ω + 25mH. Inverter efficiency is 96.48% in loss analysis with PLECS. The voltage peaks that occur during polarity transitions were eliminated by using controlled power switches instead of diodes and a stabilized output was obtained. |
