← ScienceWhich outcome occurs when rapid load changes affect a switched capacitor power supply?
A)Increased output voltage ripple appears✓
B)Enhanced electromagnetic interference shielding
C)Improved transient response stabilization
D)Decreased energy conversion efficiency
💡 Explanation
Increased output voltage ripple is a consequence because switched capacitor converters use discrete charge transfer (charge pumping); variations cause voltage fluctuations due to insufficient capacitance rather than providing constant current. Therefore ripple surges; rather than stabilize, lower efficiency or enhance shielding.
