← ScienceWhich consequence results when parasitic capacitance increases in high-frequency power inductor?
A)Reduced energy storage capability
B)Increased core saturation margin
C)Elevated power conversion efficiency
D)Higher resonant frequency peaking✓
💡 Explanation
Increased parasitic capacitance results in a lower parasitic resonant frequency due to **resonance**. The impedance peaks at that frequency because the inductive reactance cancels out with the capacitive reactance, therefore ringing is evident rather than improved performance.
