🔍 Key Concepts

• How AC propulsion drives first convert AC to DC, and then DC back to variable-frequency AC • The role of rectifiers, inverters, and thyristor-type devices in power electronics • Why simple passive components like resistors, transformers, and potentiometers cannot efficiently change AC frequency under high power

💭 Think About

• Which of these choices includes components that can perform controlled switching of power electronically, rather than just dropping voltage or current as heat? • In a modern variable-speed AC propulsion motor drive, how is motor speed controlled: by changing voltage only, or by changing frequency of the supply? Which listed components are used in such variable-frequency drives? • Think about which components you would find inside a large variable-frequency drive (VFD) cabinet on a ship’s propulsion system.

✅ Before You Answer

• Identify which option contains components used in power conversion (AC→DC→adjustable AC) rather than just voltage control or current limiting. • Eliminate any options that rely mainly on resistive control (wasting power as heat), which is not typical for modern high-power propulsion drives. • Make sure the selected components are commonly associated with solid-state power electronics for variable-frequency motor control.
