Question 556Electricity & Electronics - Assistant Engineer

The correct answer is A) provides adjustable frequency to power an AC propulsion drive motor. A cycloconverter (CCV) is a type of static power converter used in electric propulsion motor drives. The main function of a CCV is to provide a variable output frequency to the AC propulsion drive motor, allowing for adjustable speed control. This is achieved by converting the fixed-frequency AC input power to a variable-frequency AC output, which is then used to power the propulsion motor. The other options are incorrect because: B) a CCV does not provide a constant frequency output, C) a CCV converts AC power to AC power, not DC to AC, and D) a CCV is not used to convert AC to DC power in a DC propulsion drive system.
