Question:
Which of the following is not a feature of CSI fed AC motor drive?
Which of the following is not a feature of CSI fed AC motor drive?
Show Hint
CSI drives need feedback diodes for commutation—this is essential.
Updated On: May 23, 2025
- Used in high power drives
- Open loop control is not possible
- Feed-back diodes are not required
- Multi-motor operation is possible
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Features of a Current Source Inverter (CSI) fed AC motor drive:
- Suitable for high power applications
- Can operate in open loop and closed loop
- Requires feedback diodes for proper commutation
- Supports multi-motor operation
Thus, the incorrect feature is: "Feed-back diodes are not required"
- Suitable for high power applications
- Can operate in open loop and closed loop
- Requires feedback diodes for proper commutation
- Supports multi-motor operation
Thus, the incorrect feature is: "Feed-back diodes are not required"
