About this ebook

Current-limiting fuses are widely used to protect the thyristors in dc drive systems. In the event of the commutation failure when regenerating (inverting), the fuses need to interrupt in loop supplied by the ac and dc voltages acting in series which is the most difficult case for protection by fuse.

In this paper, a detailed study of the complete interruption process has been investigated by modeling of arcing process of the fuse. The effect varying the motor time constant, supply impedance, number of fuses used to clear the fault and dc machine rating to the total response for fuses protecting against the regenerative circuit internal commutation fault has been studied. The model of 200A fuse is employed in this study and fuses in series with the semiconductor devices (F1) and fuses in ac line (F2) are both considered.

I am Dr. Hidaia Mahmood Mohamed Alassouli. I completed my PhD degree in Electrical Engineering from Czech Technical University by February 2003, and my M. Sc. degree in Electrical Engineering from Bahrain University by June 1995. I completed also one study year of most important courses in telecommunication and computer engineering courses in Islamic university in Gaza. So, I covered most important subjects in Electrical Engineering, Computer Engineering and Telecommunications Engineering during my study. My nationality is Palestinian from gaza strip.

I obtained a lot of certified courses in MCSE, SPSS, Cisco (CCNA), A+, Linux.

I worked as Electrical, Telecommunicating and Computer Engineer in a lot of institutions. I worked also as a computer networking administrator.

I had considerable undergraduate teaching experience in several types of courses in many universities. I handled teaching the most important subjects in Electrical and Telecommunication and Computer Engineering.

I could publish a lot of papers a top-tier journals and conference proceedings, besides I published a lot of books in Publishing and Distribution houses.

I wrote a lot of important Arabic articles on online news websites. I also have my own magazine website that I publish on it all my articles: http://www.anticorruption.000space.com

I am an Author publishing books on kdp.amazon.comand many other book stores such as Google, Apple.com, writinglife.kobo.com, Lulu.com, feiyr.com, blurb.com, bookrix.com, notionpress.com and others .
