INVESTIGATION OF THE EFFECT OF ADDING A STIRRER AND STIRRER LOCATION ON ELECTRIC FIELD UNIFORMITY INTO REVERBERATION CHAMBER
Abstract
Reverberation chambers are
new and effective test environments used in recent years for electromagnetic
compatibility testing because of their relatively cheap realization. These chambers
are seen as an alternative to fully non-reflective testing environments in the
Pre-Compatibility testing stages (due to the high approximation of the result). Reverberation chamber testing environments have a much
cheaper installation cost than the full-reflective rooms despite the size of
their working volumes. In this study, a reverberation chamber with real
dimensions is designed with the help of electromagnetic simulation program. The
effect of the stirrer and the stirrer location in the room was investigated by
adding the stirrer to this reverberation chamber. According to the observed
results, the effect of the addition of stirrer in the room over the standard
deviation of the electric fields, ie the electric field uniformity, is averagely
1 dB. In addition, although the stirrer location in the room had little effect
on the electric field uniformity, It has been observed that the determination
of the stirrer location has a significant effect to obtain the limits proposed
by the International Electrotechnical Commission standard (IEC 61000-4-21).

YANSIMALI ODA İÇERİSİNE BİR KARIŞTIRICI EKLENMESİNİN VE KARIŞTIRICI KONUMUNUN ELEKTRİK ALAN DÜZGÜNLÜĞÜNE ETKİSİNİN İNCELENMESİ
Abstract
Yansımalı odalar görece
çok ucuza gerçeklenebilmeleri nedeni ile son yıllarda elektromanyetik uyumluluk
testleri için kullanılan yeni ve etkili bir test ortamıdır. Ön uyumluluk test
aşamalarında (sonuca ilişkin yüksek yaklaşıklıkta cevap vermeleri nedeni ile) tam
yansımasız test ortamları için bir alternatif olarak görülmektedir. Yansımalı
oda test ortamları, çalışma hacimlerinin büyüklüğüne rağmen tam yansımasız odalara
göre çok daha ucuz kurulum maliyetine sahiptir. Bu çalışmada, elektromanyetik benzetim
programı yardımıyla gerçek boyutlarda bir yansımalı oda tasarlanmıştır. Daha
sonra tasarlanan bu yansımalı oda içerisine karıştırıcı eklenerek bu
karıştırıcının ve karıştırıcının oda içerisindeki konumunun alan düzgünlüğüne
olan etkisi incelenmiştir. Gözlemlenen sonuçlara göre oda içerisine karıştırıcı
eklenmesinin elektrik alanların standart sapmasına yani elektrik alan düzgünlüğüne
olan etkisi ortalama 1 dB’dir. Bunun yanında oda içerisindeki karıştırıcı
konumun elektrik alan düzgünlüğüne oldukça az bir etkisi olmasına rağmen Uluslararası
Elektroteknik Komisyon standartının(IEC 61000-4-21) önerdiği limitleri elde
etmek için karıştırıcı konumun belirlenmesinin önemli ölçüde bir etkiye sahip
olduğu gözlemlenmiştir.
