一种用于高频应用的高效电感结构及设计指南

Operation in the high-frequency (HF) regime (3–30 MHz) has potential for miniaturizing power electronics, but designing small efficient inductors at HF can be challenging. At these frequencies, losses due to skin and proximity effects are difficult to reduce, and gaps needed to keep $\boldsymbol {B}$ fields low in the core add fringing field loss. We propose a low-loss inductor structure with step...
