Askeri uygulamalarda farklı gerilim ve güç seviyelerine ihtiyaç duyulmaklardır. Bu ihtiyaçlar sistem içerisinde çok sayıda ve farklı topolojide AA/DA ve DA/DA dönüştürücü kullanımı gerektirmektedir. Askeri amaçlı hava/kara araçlarında kullanılan güç dönüştürücülerinin genellikle küçük hacim ve düşük ağırlık gibi özelliklere sahip olması büyük önem arz etmektedir. Bu nedenle güç elektroniği dönüştürücülerinin anahtarlama frekansları gittikçe yükselmektedir. Dönüştürücülerin anahtarlama frekanslarının yükselmesi elektromanyetik gürültü seviyesinin artmasına sebep olmaktadır. Gürültü seviyesinin yükselmesi aynı kaynaktan beslenen veya yakınındaki cihazların çalışmasını olumsuz etkilemektedir bu nedenle “MIL-STD-461” askeri standardı oluşturulmuştur. Herhangi bir askeri kara/hava aracı için yapılacak dönüştürücünün ilgili standarda uyması gerekmektedir. Bu çalışmada askeri bir birim için tasarlanan AA/DA dönüştürücü “MIL-STD-461F” CE102 gereksinimi karşılayabilmesi için bir filtre tasarımı ve gerçeklenmesi anlatılmıştır. Yapılan testler sonucunda tasarlanan filtrenin standartlarda belirtilen şartları karşıladığı görülmüştür.

Electromagnetic Interference Filter Design for Power Converts Used in Military Applications

Öz

Different voltage and power levels are needed in military applications. These needs require the use of AC/DC and DC/DC converters in many different topologies in a system. It is generally important for the power converters used in military air/land vehicles to have features such as small volume and low weight. Therefore, the switching frequencies of power electronic converters are increasing. Increasing the switching frequencies of converters causes the electromagnetic noise level to increase. The increase in the noise level negatively affects the operation of devices supplied from the same source or nearby, so the "MIL-STD-461" military standard was created. The converter to be design for any military land/air vehicle must comply with the relevant standard. In this study, the design and implementation of a filter to meet the "MIL-STD-461F" CE102 requirement for an AA/DA converter designed for a military unit is described. Obtained test results showed that the designed filter met the conditions specified in the standards.
