Common-mode currents should cancel magnetically, but imbalance, leakage, control asymmetry, and faults can create net flux and drive a choke toward saturation.
Common Mode Choke Saturation Caused by Asymmetric Current Read More »
Fast GaN switching makes high frequency transformer winding capacitance a system-level EMI and isolation-current concern, not just a parasitic number.
