Which component receives 28 VDC from the ship's No Break Power Supply and converts it to 3,000 VDC?

• A. Control panel
• B. Ignition exciter
• C. Fuel pump
• D. Starter motor

Answer: (B)

Ignition systems for gas turbines rely on a high-voltage spark to ignite the fuel-air mixture. The No Break Power Supply provides a steady 28 VDC to critical ignition circuits, and the ignition exciter is the device that takes that low-voltage input and converts it into a high-voltage pulse, typically around 3,000 VDC, delivered to the spark plug. That high voltage is what creates the spark across the electrode gap in the combustion chamber to ignite the fuel. The other components don’t perform this voltage up-conversion. The control panel handles signals and settings, the fuel pump operates at its own low-voltage supply to move fuel, and the starter motor uses the 28 VDC to turn the engine but doesn’t generate the high-voltage spark needed for ignition.
