Discussion
Which of the following circuit can NOT be used for obtaining variable frequency supply for induction motor?
Answer: D
A chopper cannot be used to obtain a variable frequency supply for an induction motor. A chopper is a DC to DC converter and gives a variable DC voltage, but it does not produce an alternating output.
A cycloconverter changes AC at one frequency to AC at a lower frequency directly, and voltage source and current source inverters change DC to AC of variable frequency. So the fourth option is the answer.
