الملخص

تستخدم مبدلات إلكترونيات القدرة المكونات المغناطيسية عالية التردد (المحاثات والمحولات) على نطاق واسع. وتعتمد كفاءة وكثافة الطاقة لهذه المبدلات على تكنولوجيا تصميم اللفات لتقليل خسائر التردد العالي. يقدم هذا البحث دراسة تحليلية لتأثيرات القشرة والقرب في اللفات، حيث يحاكي مقاومة التيار المتردد كدالة لسمك الطبقة. وبشكل أكثر تحديدًا، تمت مراجعة ومناقشة التحليل النظري ومحاكاة رقائق النحاس ولفائف ليتز للتطبيقات عالية التردد. أيضًا، تتم مقارنة الأداء على أساس عامل مقاومة التيار المتردد ومحاثة التسرب. كما تم تصميم المكونات المغناطيسية على النحو الأمثل مع مقاومة منخفضة للتيار المتردد وتحريض التسرب للحصول على كفاءة أعلى ومحولات تحويل عالية الكثافة.
