← ScienceWhich mechanism causes voltage overshoot in a boost converter circuit?
A)Inductor energy release rate
B)Gate driver propagation delay
C)Capacitor equivalent series resistance
D)Diode reverse recovery energy✓
💡 Explanation
Diode reverse recovery injects charge into the capacitor, causing ringing; the mechanism is parasitic capacitance discharge. Because the diode cannot instantly switch off, discharging parasitic capacitance creates a current spike, therefore leading to a voltage overshoot, rather than controlled voltage changes.
