← TechnologyWhich outcome occurs when a MOSFET used in a boost converter experiences avalanche breakdown?
A)Increased power dissipation losses✓
B)Improved switching frequency stability
C)Enhanced gate oxide integrity
D)Reduced electromagnetic interference (EMI)
💡 Explanation
Increased power dissipation losses occur because avalanche breakdown causes a large current to flow through the already stressed MOSFET, inducing significant resistive power loss as heat; therefore, the MOSFET can fail, rather than performing desired voltage transformation without overheating under normal load.
