← TechnologyWhich outcome occurs when parasitic capacitance in converter circuit rapidly switches?
A)Increased electromagnetic interference emissions✓
B)Reduced switching losses in transistors
C)Improved power factor at the input
D)Decreased thermal stress on capacitors
💡 Explanation
When parasitic capacitance switches rapidly, displacement current occurs because dv/dt generates high-frequency oscillations, leading to increased electromagnetic interference (EMI). Therefore increased EMI emissions result, rather than decreased losses, improved power factor, or reduced stress, which are consequences of circuit optimization, not parasitic effects.
