Three-phase asynchronous motors are widely used in many areas of industry. Unplanned malfunctions in the motor can cause the entire system to become inefficient. Detecting and intervening the malfunctions before they grow has a direct impact on the life of the…

Asenkron motorlar, endüstrideki en yaygın kullanılan motorlardır. Çok avantajlı bir yapıda olduklarından üretim hatlarının her noktasında bulunurlar. Bu motorların arızalarını hızlı ve kolay bir şekilde tespit etmek arzu edilir. Bu makalede, asenkron motorları…

In this study, mathematical modeling of outer rotor brushless direct current motor (BLCD) is performed. Brushless direct current motor is highly preferred in industrial applications when compared the other motor types with considering advantages and disadvanta…

Enerji günümüzün vazgeçilmez ihtiyaçlarından birisidir. İhtiyaca göre farklı tiplerde enerji kaynakları kullanılmaktadır. Ancak fosil kökenli yakıtların tükenebilir enerji kaynakları olması ve çevresel etkenlerden dolayı yenilenebilir enerji kaynaklarının önem…

This study includes the design of quadratic cascade DC/DC boost converter with PI controller. Two or more cascade boost converters have been used to increase system efficiency. Advantages of the proposed converter compared to the conventional boost converter a…

In this study, a single switch cascade DC/DC boost converter has been preferred instead of conventional cascade DC/DC boost converter to reduce cost and provide simple system control. High-performance controller design for DC/DC converters is the most importan…

[Cp2V{S2CN(CH2)4O}]+ and [(η5-C5H4Me)2V{S2CN(CH2)4O}]+ complexes are optimized B3LYP/GEN level (GEN keyword is mean that LANL2DZ basis set for metal atom and 6-31G(d) basis set for S, O, N, C and H atoms) in gas phase. The aim in this study, the molecular st…

Güç sisteminde akım ve gerilimin dalga formunun sinüsoidal formda olması gerekir. Fakat bu her zaman mümkün olmaz. Non-sinüsoidal gerilim veya elemanlar güç sisteminde harmoniklerin oluşmasına sebeb olur. Harmonikler güç sisteminde, ek ısıl kayıplara, rezona…

In this study, a thermoelectric generator (TEG) system is designed for the generation of electricity from solar energy. A temperature difference between surfaces of TEG must be achieved for electricity generation. Heating is provided by a solar-powered two-p…

Complexity in the behavior of asphalt binders are further escalated with geopolymer (fly ash and the alkali liquid) modification thus, making it difficult to predict the performance of the binder accurately. This study employs artificial neural network model…
