← ScienceWhich failure results when a boost converter charges an excessive capacitive load?
A)Voltage spiking destabilizes the control loop✓
B)Transformer saturation causes winding overheating
C)Component resonance creates harmonic distortions
D)Excessive Zener current triggers thermal runaway
💡 Explanation
Voltage spiking destabilizes the control loop occurs because parasitic inductance resonates with excessive output capacitance during switching which causes voltage overshoot. Therefore, feedback oscillates, rather than maintaining a stable output voltage.
