← ScienceWhich mechanism prevents runaway current when cascading resonant inductive converters approach critical power transfer?
A)Decreased impedance matching efficiency
B)Synchronized inverter phase adjustments
C)Increased parasitic winding capacitance
D)Nonlinear inductor core saturation✓
💡 Explanation
Nonlinear inductor core saturation limits current when resonant converters approach critical transfer, because that causes decreased magnetizing inductance which throttles current oscillations; therefore saturation prevents a catastrophic current spike, rather than impedance changes alone handling the surge.
