← ScienceWhich risk increases when a switched-mode power supply (SMPS) capacitance degrades?
A)Increased electromagnetic interference (EMI)✓
B)Improved transient response time
C)Decreased output voltage ripple
D)Enhanced power factor correction
💡 Explanation
Increased EMI occurs when capacitance degrades due to less effective filtering via capacitive reactance impacting impedance. Increased EMI is a result of higher ripple current because the capacitance is insufficient, rather than improving performance characteristic.
