“…FC-MLI mirip dengan NPC-MLI. Satu-satunya perbedaan adalah bahwa dibandingkan menggunakan dioda, clamping dilakukan dengan menggunakan kapasitor [7], [18]. Kapasitor di sisi DC terhubung mirip dengan struktur tangga, di mana tegangan berbeda di setiap kapasitor dan kapasitor berikutnya.…”

Multilevel Inverter (MLI) merupakan salah satu jenis inverter yang memiliki gelombang tegangan keluaran bertingkat. Meskipun lebih baik dari inverter konvensional, MLI yang beroperasi pada frekuensi rendah masih mengandung harmonisa orde rendah pada tegangan dan arus keluaran yang berdampak negatif pada sistem kelistrikan. Untuk mengatasi masalah ini, banyak peneliti telah mengembangkan berbagai teknik kontrol dan pada modulasi inverter untuk mengurangi harmonisa dan meminimalkan kerugian penyaklaran dengan tujuan mengoptimalkan efisiensi inverter. Selective harmonic elimination pulse-width modulation (SHEPWM) adalah kontrol paling optimal dari semua metode yang telah dikembangkan untuk menghilangkan harmonisa orde rendah dari tegangan keluaran inverter. Namun, ada tantangan dalam proses analisis MLI menggunakan SHEPWM karena penyelesaian persamaan yang sulit. Bio-inspired intelligent algorithms (BIA) digunakan untuk memecahkan masalah ini. Paper ini menjelaskan secara lengkap review dari berbagai penelitian yang telah dilakukan sebelumnya terkait dengan prinsip operasi sembilan jenis BIA dan aplikasinya dalam mereduksi harmonisa. Kesimpulan dibuat berdasarkan informasi yang diambil dari literatur. Semua informasi penting dalam paper ini mengenai reduksi harmonisa pada MLI akan membantu penelitian di masa depan untuk merancang sistem konversi daya yang efisien. Kata Kunci— Bio-inspired algorithm, harmonisa, multilevel inverter, optimalisasi, selective harmonic elimination.

“…Interfaces between two different materials not only have rich physics, such as superconductors, , quantum spin hall effects, and topological phases, but also are fundamental compositions of functional devices utilized for various applications, including energy conversions, catalysis, − information processing, and so on. To reveal the properties of interfaces, a determination of the interface structures is of great importance for further exploration of electronic properties as well as novel physics and applications.…”

The heterostructure CdS/CdTe is one of the most important interfaces in solar energy cells, however, its exact structure is not well-known due to the large lattice mismatch, thus hindering the studies of interfacial properties. In this paper, we present a scheme to explore the interface structures by combining the differential evolution (DE) algorithm and the neural network potential. A high-accuracy neural network potential is trained to describe the interatomic interactions, and then the interfacial structures are searched using our DE program that started from a CdS/CdTe interface model that consists of about 1740 atoms. We identify a series of interfacial structures with defects and assess their stabilities by considering the interfacial energies. We find that the CdS-like interface I is generally energetically more favorable and prefers to be defect-free under the Cd-poor condition. Therefore, the Cd-poor condition might be beneficial for improving the solar cell efficiencies by suppressing possible defect recombination at the interface. Our work provides a general scheme to study structures of complex interfaces with a large number of atoms.
