← TechnologyWhich limitation arises when excessively increasing stray capacitance within a resonant power converter circuit?
A)Elevated switching losses during transistor transition✓
B)Increased core saturation risk in transformer
C)Decreased electromagnetic interference shielding
D)Reduced output voltage ripple suppression
💡 Explanation
When stray capacitance increases excessively, the resonant circuit stores more energy because energy stored is proportional to capacitance and voltage squared, and discharging takes longer during each cycle, elevating switching losses. Therefore, switching losses increase, rather than promoting core saturation, decreasing shielding, or suppressing ripple, mechanisms governed by different factors.
