Question 57Electricity & Electronics - 1st Asst/Chief
70% to passWhat type of electric propulsion system converter is shown in the illustration? Illustration EL-0155

The correct answer is C) synchroconverter. A synchroconverter is an electric propulsion system converter that uses a synchronous generator to convert alternating current (AC) power to direct current (DC) power. This type of converter is commonly used in marine applications, including US Coast Guard vessels, to power electric propulsion systems. The other options are incorrect because: A) Pulse width modulation (PWM) converters are used to control the speed of AC motors, not to convert AC to DC. B) Cycloconverters are used to convert AC to AC at a different frequency, not to convert AC to DC. D) Controlled rectifier converters are used to convert AC to DC, but they do not use a synchronous generator like a synchroconverter.
