← ScienceWhich risk increases when pulse width modulation exceeds design capacitance?
A)Increased gate driver thermal runaway✓
B)Reduced electromagnetic interference emission
C)Improved output voltage rise time
D)Decreased overall circuit efficiency
💡 Explanation
Exceeding capacitance triggers increased gate driver thermal runaway because higher switching frequency causes greater capacitive power dissipation by dielectric heating, therefore, the heat cannot dissipate quickly enough, rather than efficiency improvement or reduced interference.
