摘要: Coss nonlinear behavior of modern power FETs challenges large-signal model development used for DC-DC converter efficiency optimization. Small-signal data available in vendor's specifications could mislead and cause errors. Paper reviews existing modeling approaches suggests accurate practical large signal models popular wide bandgap (WBG) based on experimental test setup.
