← TechnologyFor an LED display using PWM brightness control which consequence results from exceeding diode reverse recovery time?
A)Reduced average LED forward voltage
B)Increased EMI and power loss✓
C)Lowered LED forward current overshoot
D)Enhanced color blending accuracy
💡 Explanation
Exceeding a LEDs reverse recovery time during PWM causes increased EMI and power loss because reverse current flows until the diode blocks, according to the reverse recovery mechanism therefore increasing noise, rather than lower voltage, limited overshoot, or more accurate blending.
