Elektrikli Araçların Kablosuz Güç Transferi Sistemleri için Farklı Transformatör Modellerinin Tasarımı ve Analizi

Kablosuz güç aktarımı, elektrikli araçların, implante edilmiş tıbbi cihazların vb. kablosuz şarjın geniş uygulamaları nedeniyle gelişmekte olan bir teknolojidir. Tasarımcıların kablosuz güç aktarımını (KGA) daha verimli ve kullanıcı dostu haline getirebilmeleri için bu uygulamaların önemli noktalarını bilmeleri gerekmektedir. KGA sistemninin tasarımı için yüksek frekanslı bir transformatörün uygun tasarımı en öenmli adımdır. Bu yüksek frekanslı transformatörlerden güç aktarımı sırasında minimum kayıpları elde etmek için endüktif güç aktarım ilkesi kullanılmaktadır. Bu çalışmada, elektrikli araç şarjı için tasarlanmış yüksek frekanslı bir transformatörün tasarımı ve analizi sunulmuştur. Bu tasarımda, primer ve sekonder bobinler arasındaki farklı mesafelere sahip çeşitli transformatör konfigürasyonları, bağlantı katsayısı ve karşılıklı endüktans gibi kablosuz güç aktarım parametreleri için analiz edilmiştir. Tasarımlar, Sonlu Elemanlar Yöntemine dayalı çözüm gerçekleştiren ANSYS Maxwell yazılımı kullanılarak simüle edilmiş ve sonuçlar elde edilmiştir. Son olarak bu çalışmada, KGA sistemi için dairesel ve dikdörtgen tip transformatör tasarımlarının analiz sonuçları karşılaştırılmış ve optimum tasarım belirlenmeye çalışılmıştır.
