LLC谐振变换器中的平面变压器：高频边缘损耗建模

Fringing losses play a detrimental role in high-frequency transformers. The tendency toward higher power density and miniaturization of power converters leads to higher switching frequency and enforces the use of low-profile components such as gapped planar transformers. Due to the air gap, lower magnetizing inductance and better regulation of LLC (Lm, Ls, Cs) can be achieved, but fringing fluxes ...
