← ScienceWhich outcome occurs when capacitance increases excessively in power electronics?
A)Increased inrush current at startup✓
B)Lower diode reverse recovery losses
C)Reduced gate driver oscillations
D)Higher electromagnetic interference (EMI)
💡 Explanation
Increased capacitance causes greater stored charge; discharging this during startup creates extreme inrush current because capacitor voltage changes slowly. Therefore, high initial current is observed, rather than EMI reduction from smaller capacitors or improved diode performance.
