Transformer utilization factor of a centre tapped full wave rectifier is_________

Electronics and Communication Engineering (ECE) : Electronic Devices and Circuits - Quiz(MCQ)

0.623

0.625

0.678

0.693

Correct Answer : Option (D) : 0.693

Explanation : Transformer utilisation factor is the ratio of AC power delivered to load to the DC power rating. This factor indicates effectiveness of transformer usage by rectifier. For a half wave rectifier, it’s low and equal to 0.693.
