← TechnologyWhich outcome occurs when rapid gate voltage changes induce high dI/dt in a MOSFET powering an inductive load?
A)Increased electromagnetic interference (EMI)✓
B)Enhanced gate oxide layer integrity
C)Improved switching efficiency overall
D)Reduced power dissipation significantly
💡 Explanation
Increased EMI occurs because parasitic inductance combined with high dI/dt causes significant voltage ringing due to inductive kickback, therefore generating unwanted electromagnetic radiation, rather than improving efficiency; gate stress increases under these conditions.
