The efficiency of a modern drive converter at rated load is typically about
Answer: C
Correct answer: 97 to 98 per cent
A modern voltage source drive loses two or three per cent at rated load, divided between conduction and switching in the semiconductors with a small contribution from the magnetics and the control supply. The figure falls at light load, where the fixed losses become a larger share, which is worth remembering when a drive spends its life part-loaded.
