高频变压器寄生电容的实验提取方法

Parasitic capacitances of the high-frequency (HF) transformer used in dc-dc converter impact harmonic analysis of the transformer and interactions with the converter. Resonant frequencies of open- and short-circuit impedances characteristics (ICs) have been widely used to extract parasitic capacitances of HF transformers, but it was reported that some resonant frequencies were unobtainable as they...
