Modular multilevel matrix converter is a type of used in medium-voltage ac-ac power conversion. Controlling the energy content arms prerequisite for proper operation, and at same time challenging control task. So far, there are several approaches presented literature that successfully deal with challenge. However, almost all them fail when it comes to simplicity implementation, ease understandi...

Bu makalede, değişken bir çıkış gerilimi ve kademeli olarak değişen frekansı elde etmek için tek fazlı matris dönüştürücü ile birlikte Z-kaynak ağı kullanılan alternatif akım-alternatif akım (AA-AA) yapısı incelenmiştir. yapısında, hem düşürülebilmekte de yükseltilebilmektedir. Matris dönüştürücü, doğrudan AA-AA dönüşüm yaparken anahtarlama stratejisi frekansını değiştirme imkânı sağlamaktadır....

In this article, an improved space vector pulsewidth modulation strategy for matrix converter is proposed under unbalanced input voltages. First, to obtain the higher output voltage, two novel strategies based on linear superimposition principle are presented by modifying magnitude of reference voltage and current vectors. Second, in order evaluate performance strategy, harmonic characteristics...

During the last two decades, it has been seen that power conversion from one form to another of energy was a serious issue in electronics. After production converters such as rectifiers convert AC-DC, inverters DC-AC, voltage regulators, choppers, and cycloconverters make possible conversion. In 1980, Venturini presented concept Matrix Converter electronics; consists bidirectional IGBT switches...

Matrix Converters are becoming popular in industrial applications due its better performance than the conventional VSI converters. The advantages of Matrix Converters are bidirectional current flow, adjustable displacement angle and sinusoidal input current and output voltage. Two control schemes used to control the speed of Induction motor. They are Field Oriented Control and Direct Torque Con...

for beneficiation of converter slag, the role of surface phenomena on slag composition was studied. this work includes some experimental data, which were measured for basic oxygen steel (bos) slag in isfahan steel plant. all data were collected on site in the plant. the results support the idea that surface activity plays a major role in converter slag formation. it was also a new finding that ...

Pulse width modulation strategies have been developed for indirect matrix converters (IMCs) in order to improve their performance. In indirect matrix converters, the LC input filter is used to remove input current harmonics and electromagnetic interference problems. Unfortunately, due to the existence of the input filter, the input power factor is diminished, especially during operation at low ...
