Which risk increases when a boost converter circuit enters discontinuous conduction mode at elevated temperatures?

💡 Explanation

Increased MOSFET voltage overshoot occurs due to parasitic inductance effects exacerbated by discontinuous conduction, because the inductor current abruptly drops to zero. Therefore, voltage spikes increase; rather than core saturation reducing, as core losses heat the system further.
