“…This paper has shown no prototype, and the theoretical analysis shows that the efficiency conversion is 97.8 % for the 2-level converter and 97.6% for the NPC converter. In [23], the design of a three-phase AC-AC NPC converter connected between the grid and the AC loads has been proposed. From the carried-out analysis, an efficiency of 88% has been declared with a power of 610 W and DC-bus of 100 V. The single-phase AC-AC 3 kW T-Type converter has been analyzed and implemented in [24] for UPS applications.…”

In modern applications, such as variable frequency electric drives, aircraft propulsion, electric vehicles, and uninterruptible power supply units, high power-dense, and efficient AC-AC power converters are the key to reducing power losses, thus limiting the overall costs, and improving the system's reliability. Power electronic equipment can be enhanced thanks to the continuous evolution of conversion topologies and advancements in power semiconductor technology. The design and the optimization strategy of the AC-AC 5-Level converter, called Interleaved 3-Phase 5-Level E-Type Back-to-Back Converter (I-3Φ5L BTB E-Type Converter), has been proposed in this paper. The converter is analyzed and experimentally characterized to prove the configuration's high efficiency and high-power density. An introduction to the characteristics of the I-3Φ5L BTB E-Type Converter is described, and afterward, the optimization methodology to design the multilevel converter is presented. The converter prototype is illustrated, which achieves a peak efficiency of 98.2% and a total weight of 6.18 kg using hybrid technology for power semiconductors..
