Which mechanism causes voltage overshoot when a MOSFET switches off inductive load with parasitic capacitance?

A)Resonance between inductance and capacitance
B)Reverse recovery current in the diode
C)Gate charge from Miller effect
D)Ohmic losses in the inductor

💡 Explanation

When a MOSFET switches off an inductive load, energy stored in the inductor transfers to the parasitic capacitance, causing resonant oscillation because energy oscillates between the inductance and capacitance, leading to a voltage overshoot. Therefore resonant voltage overshoot results, rather than diode, gate, or ohmic effects which are separate phenomena.
