The diode D3 conducts from
A. 0 to 270 degrees
B. 270 to 390 degrees
C. 270 to 450 degrees
D. 270 to 360 degrees
Answer:A
The diode D3 conducts from
A. 0 to 270 degrees B. 270 to 390 degrees C. 270 to 450 degrees D. 270 to 360 degrees
Explanation: It conducts from 270 to 450, for 120 degrees. D1 starts conducting first (from 30 degrees) as it will be the most positive as it is connected to the R phase & likewise. 6. In a three-phase half wave diode rectifier using 3 diodes,
