← ScienceWhich consequence results when parasitic capacitance resonates strongly in a boost converter?
A)Increased switching MOSFET gate leakage
B)Increased inductor core saturation losses
C)High-frequency EMI noise signal generated✓
D)Erroneous microcontroller PWM signal trigger
💡 Explanation
Strong resonance causes high-frequency ringing due to parasitic capacitance discharge through circuit inductances and resistances via the LC oscillation mechanism, therefore EMI issues arise, rather than the other options which require over-voltage effects or gate failure because gate capacitance acts as a filter.
