Which effect occurs when a diode's reverse recovery time exceeds the available commutation time in a high-frequency inverter?

A)Shoot-through fault increases
B)Diode forward voltage reduces
C)Inverter efficiency improves overall
D)Gate driver signal strengthens

💡 Explanation

Shoot-through current increases because minority carriers cause reverse current during the diode's reverse recovery time, leading to momentary short-circuit if not fully cleared during available commutation time. Therefore shoot-through increases rather than efficiency improving under this constraint.
