Which risk increases when an inverter's flyback diode current limit is exceeded?

A)Excessive electromagnetic interference generation
B)Premature diode reverse recovery failure
C)Transformer core saturation vulnerability
D)Oscillator frequency synchronization drift

💡 Explanation

Exceeding a flyback diode's current limit causes overheating due to increased power dissipation. This leads to thermal runaway, increasing the risk of premature diode reverse recovery failure, because the increased temperature degrades the semiconductor junction. Other outcomes are caused by different mechanisms, rather than heat.
