“…Symmetrical systems are used to create fault‐tolerant systems, while binary and trinary configurations are used to achieve more levels in the output voltage with fewer switches. This article discusses several CHB topologies based on the number of switches [30]. Typically, inverters operate by switching electronic switches that are controlled by PWM techniques.…”

This article explores the integration of artificial intelligence (AI) applications into project‐based learning (PBL) education as a means to enhance students' education. Specifically, the implementation of AI in the context of power generation is addressed, focusing on achieving power generation at minimum wind velocity and classifying turbine faults using AI techniques. The researchers have proposed a novel generating unit which is going to generate 1 KW of electric power at a specific flow rate of air and the generated power will be stored in the battery bank through the charge controller and then the load is driven from the battery through an inverter. Iron or core losses (Hysteresis, Eddy Current losses) can be acknowledged as one of the major reasons for the inefficiency of conventional generators, therefore anovel coreless model generator was proposed which also improved efficiency and reduces drag. Wind Turbine prototype was fabricated and deployed for the testing and validation of the proposed novel design. The design produced outstanding power ratings and electrical generation characteristics compared with other existing strategies at minimal air flow. Results proved that the proposed coreless axial flux generator has the capability to produce a better power rating compared with the existing wind turbine generators. Proposed Axial flux achieved 10.73 watt power at wind velocity at around 80 rpm. At a wind velocity of 10 m/s and around 800 rpm 313–330 kwh was produced by the proposed generator while the conventional generator produced around 300 kwh. The proposed generator design performed 35% better in terms of production efficiency under load and no load conditions. Moreover, faults in turbines are very common due to the various temperatures, therefore the faults have been classified using state‐of‐the‐art AI‐based classifiers. A comparison of space vector modulation (SVM) and Naive Bayes classifiers was performed in the study to classify wind turbine faults. It was found that both classifiers performed well in achieving high accuracy. SVM achieved a slightly higher accuracy of 0.9861 compared with Naive Bayes, which achieved an accuracy of 0.967. Based on the results, it can be inferred that SVM may be a more suitable classifier for wind turbine fault classification. The case study results demonstrated the potential of AI applications in PBL education, offering students a multidisciplinary learning experience that enhances their technical knowledge, problem‐solving skills, and teamwork abilities.

“…CHB-MLI dapat diklasifikasikan menjadi dua jenis berdasarkan nilai sumber DC, simetris dan asimetris. CHB-MLI simetris memiliki tegangan yang sama pada setiap sumber sedangkan CHB-MLI asimetris memiliki nilai tegangan yang berbeda [23]. Tabel 5 dan Tabel 6 menunjukkan konfigurasi topologi rangkaian [24] dan penyaklarannya.…”

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.

Inverter is a device to convert Dc current voltage into AC current voltage. In this article, the inverter is designed using the H-Bridge configuration. The advantage of this configuration is that there is no need for diodes and capacitors to balance the voltage. The main components in designing this inverter are the Arduino Nano, the IR2103 IC, and also the MOSFET. The switching method used is SPWM with H-Bridge configuration which is controlled by 2 IC IR2103. Based on the test results, the output voltage of this inverter is 7.45 Volts. With a DC voltage of 12 Volts. With the use of an oscilloscope that is used to measure the output waveform from the switching results of the MOSFET, the signal is still in the form of a square wave. To make a sine wave, an inductor filter is needed which functions to produce a signal to become a sine wave, and to keep the frequency at 50Hz. The voltage generated from the step-up transformer can be adjusted by rotating the feedback trimpot. The resulting voltage is 88 Vac to 260 Vac. and can accommodate a maximum load of 250 Watts. This inverter is also equipped with a PZEM-004T sensor which functions to read voltage, current, frequency and power data.
