Assertion (A): Dead time introduces a voltage error worst at low speed.
Reason (R): The lost volt-seconds are a fixed quantity per switching.
Select the correct option.
Answer: A
Correct answer: Both A and R are true, and R is the correct explanation of A
Both are true and the reason gives the mechanism. The volt-seconds lost at each switching are fixed by the dead time and the link voltage, not by the output being produced. At high output that fixed loss is a small proportion; at the low voltage of low-speed running it is a large one, so the distortion and the torque ripple are worst there.
