Kablo karmaşıklığını ve cihazlar arasındaki
bağlantı terminali farklılığını ortadan kaldırmayı amaçlayan kablosuz güç
aktarım sistemleri günümüzde cep telefonu, diş fırçası, tıraş makinası ve
elektrikli taşıtlar gibi birçok alanda geniş kullanıma sahiptir. Yapılan
çalışmalar aktarılan güç miktarının ve sistem veriminin alıcı-verici bobinler
arasındaki mesafeyle ters orantılı değiştiğini göstermektedir. Bu sebeple kablosuz
güç aktarım sistemi tasarlanırken alıcı-verici bobinler arasındaki mesafenin hesaba
katılması ve en uygun değerin belirlenmesi gerekmektedir. Bu hesap sonlu
elemanlar analizi yapan ve uzmanlık gerektiren karmaşık yazılımlarla mümkün
olabilmektedir. Bu çalışmada, kullanıcılara kablosuz güç aktarım sistemi
tasarımı yaparken alıcı-verici bobin arasındaki mesafeyle verim ilişkisini analiz
etme imkânı veren, düşük maliyetli, basit kullanımlı karşılıklı endüktans hesaplama
aracı sunulmaktadır. Geliştirilen hesaplama aracı hava nüveli özdeş iki bobin
arasındaki farklı mesafe ve hizalanma değerleri için karşılıklı endüktans ve
bobinlerin öz endüktans değerlerinin hesaplanmasında kullanılabilen benzersiz
bir uygulamadır. Bunlara ilaveten tasarlanan görsel ara yüz sayesinde, bobinlerin
konumu 3-boyutlu koordinat sisteminde değiştirilebilir ve karşılıklı endüktans
değerinin mesafeyle değişimini gösteren eğriler oluşturulabilir.
