← TechnologyWhich risk increases when parasitic capacitance affects PWM-controlled LEDs?
A)Overlapping forward recovery current✓
B)Unintended resonant circuit formation
C)Increased reverse recovery time
D)Decreased luminous flux efficacy
💡 Explanation
Overlapping forward recovery current issues increase because parasitic capacitance causes stored charge to discharge during PWM transitions, leading to current spikes; therefore, it is more forward recovery related rather than simple luminance or resonance given the switching context.
