Which risk increases when a DC-DC boost converter operates with discontinuous conduction mode and insufficient output capacitance?

💡 Explanation

When a boost converter operates with discontinuous conduction and low output capacitance, the output voltage ripple increases because the capacitor lacks sufficient charge storage to smooth voltage variations between switching cycles. Therefore increased voltage ripple results, rather than core saturation, MOSFET breakdown, or inductor overheating, which arise from distinct failure modes.
