← TechnologyWhich outcome occurs when a power diode's reverse recovery time is exceeded amid resonant switching?
A)Increased electromagnetic interference (EMI)✓
B)Reduced switching losses significantly
C)Improved circuit power factor
D)Decreased device junction temperatures
💡 Explanation
Increased EMI occurs because exceeding the diode's reverse recovery time causes rapid, high-magnitude current spikes due to snap-off effect. These spikes generate high-frequency harmonics, therefore increasing EMI, rather than improved switching, which demands slower switching to manage the current overshoot well.
